Non Technical Summary
The analytical separation of organic compounds originating from a wide range of natural or synthetic sources by gas chromatography (GC) as well as their subsequent identification via coupled mass spectrometry (MS) are well established technologies. The front-end additions to GC available from Gerstel Inc. offer unique improvements in sample preparation/introduction that result in unprecedented increases in sensitivity in the analysis. With the support of this proposal we will acquire a combined gas chromatograph/mass spectrometer with front-end Gerstel line for automated sample preparation/introduction and increased sensitivity. The instrument will be hosted in the Analytical Biochemistry Core (ABC) Lab in the Davis College of Agriculture, Natural Resources and Design at West Virginia University. The requested Gerstel GC/MS system allows extremely sensitive detection and accurate quantification of metabolites and organic compounds produced by or found in plants, insects, animals, food, microbes, soil, and water. In addition, the unique Gerstel technology allows sample collection under different conditions (i.e. different climates) and from different matrices (i.e gaseous vs aqueous) and environments (i.e. lab vs field, air vs soil). The acquisition of the requested instrumentation thus represents a game-changing opportunity to advance fundamental and applied research, and education of students at West Virginia University. The research enabled is extensive, multidisciplinary and from different backgrounds including plant science, biochemistry, textile science, entomology, genetics, plant pathology, soil science, environmental microbiology, food science, and water science. Availability of the Gerstel technology will improve the training of students within their research projects and the curriculum of classes, enhance STEM Camps for middle-school students, support emerging research programs of young faculty and future recruiting efforts, and help to attract additional external research funding. The Gerstel GC/MS will be operated and maintained by a lab technician within the Analytical Biochemistry Core Lab which is affiliated with the WVU Shared Research Facilities, and the Gerstel GC/MS will thus also be available other users in and outside WVU.

Goals / Objectives
The major goal of this proposal is to acquire a combined gas chromatograph/mass spectrometer with a front-end Gerstel line for automated sample preparation/introduction and increased sensitivity. The instrument will be hosted in the Analytical Biochemistry Core (ABC) Lab in the Davis College of Agriculture, Natural Resources and Design at West Virginia University. The requested Gerstel GC/MS system allows extremely sensitive detection and accurate quantification of metabolites and organic compounds produced by or found in plants, insects, animals, food, microbes, soil, and water. In addition, the unique Gerstel technology allows sample collection under different conditions (i.e. climate scenarios) and from different matrices (i.e gaseous vs aqueous) and environments (i.e. lab vs field, air vs soil). This proposal includes the following specific objectives:Objective 1:Acquisition, delivery and installation of the Gerstel GC/MS system in theAnalytical Biochemistry Core (ABC) Lab in the Agricultural Sciences Building at West Virginia University.Objective 2:Technical trainingof the lab technician and PI/CoPIs on the new Gerstel GC/MS system.Objective 3: Implementation of the Gerstel GC/MS system and technology into ongoing and new research projects ofPI/CoPIs and collaborators.Objective 4: Integrate the use of the Gerstel GC/MS system into the curriculum of undergraduate and graduate classes as well asSTEM camps for middle-school students.Objective 5: Through the affiliation with theWVU Shared Research Facilities make the Gerstel GC/MS technology available to other internal WVU users as well as additional external users.
Project Methods
The analytical separation of organic compounds originating from a wide range of natural or synthetic sources by gas chromatography (GC) as well as their subsequent identification via coupled mass spectrometry (MS) are well established technologies. The front-end additions to GC available from Gerstel Inc. offer unique improvements in sample preparation/introduction that result in unprecedented increases in sensitivity in the analysis. This proposal now allows us toacquire a coupled gas chromatograph (Agilent Technologies 7890B series) / mass spectrometer (Agilent Technologies 5977B Inert Plus MSD Turbo EI) with a mounted front-end Gerstel product line. Three Gerstel modules form the core of the front-end additions: 1) the Multipurpose Sampler, an autosampler and sample preparation robot, 2) the Thermal Desorption Unit (TDU), that allows introduction of a wide range of different samples (liquids, solids, adsorbent-filled tubes, Gerstel Twister®, Gerstel Thin Film Solid Phase Microextraction) and subsequent thermal desorption, and is connected to 3) the Cooled Injection System CIS 4C, a high-performance cryo-trap that after thermal desorption of injected samples refocuses the analytes before transferring the entire sample by temperature vaporization to the GC which results in excellent recovery and separation of peaks, and extremely low detection limits. In addition to its extremely high sensitivity the design of the front-end Gerstel line offers a diverse and unique set of options for sample collection and preparation: 1) liquid samples can be loaded by syringe or from Micro-Vials via thermal extraction; 2) the Automated Dynamic Headspace Module can be used to extract and concentrate VOCs from liquid or solid samples by trapping the headspace above the sample on adsorbent-filled tubes that are subsequently inserted into the TDU; 3) the Automated Solid Phase Micro Extraction (SPME) module offers a standard technique for high throughput extraction and concentration of VOCs; 4) the Twister® Stir Bar Sorptive Extraction (SBSE) and the Thin Film-Solid Phase Micro Extraction (TF-SPME) technologies provide 1000-fold lower detection limits due to the increased surface area and adsorbent phase volume. Both devices can be used in headspace mode for VOC collections from the gas phase, or in immersion mode for compound collection from aqueous samples. The devices are then inserted into the TDU where bound compounds are released by heating for analysis by GC/MS. The subsequent cryo-trapping of released compounds enables analysis of entire samples thus further adding to the sensitivity of detection. A unique feature of Twister® Stir Bar and TF-SPME is the ability to perform VOC collections under field/environmental conditions thus overcoming the need to first sample material (i.e. plants, insects, water) for a later lab-based analysis. Besides the described front-end additions Gerstel also offers an Olfactory Detection Port (ODP) downstream of the GC that allows to split compounds that have been separated in a defined ratio for the subsequent parallel MS and human olfactory analysis.The Gerstel GC/MS system will facilitate the collection and identification of organic compounds from a wide variety of organisms and samples with extremely low detection limits, under different conditions (i.e. climate scenarios) and from different matrices (i.e. gaseous vs aqueous) and environments (i.e. lab vs field, air vs soil).

Outputs
Target Audience:The outcome of the research enabled by the acquisition of the Gerstel GC/MS system through this grant hasbeen initially and immediately relevant and of interest to audiences within the research communities of the plant science, biochemistry, textile science, entomology, genetics, plant pathology, soil science, microbiology, and food science. Upon the installation of the Gerstel GC/MS system in early 2022 research projects in the listed areas have begun to utilize this new technology or have initiated new experiments that will now utilize this technology. Results of respective research projects and the gained knowledge have already been communicated to research communities via presentations at scientific conferences, have been included in grant proposals, and havebeenincluded into a first manuscripts that has already been published and additional manuscripts in preparation that will be submitted for publication in respective discipline research journals. In the long run, however, the knowledge gained, and the new protocols, strategies and products developed within these various research projects will also target and benefit audiences beyond the research communities. Since the PI/CoPIs and collaborators are fully committed to WVU's land grant mission and thus consider it essential to make the outcomes of research enabled by the obtained instrument also available to the general public, farmers and other stakeholders through outreach activities. Towards this goal we have teamed up with members of the WVU Extension Service for respective outreach activities such as the WVU Cider School and the WV Master Gardener Conference, as well as with the WVU Reed College of Media for some interviews to make the findings of our research available to a broader audience, and to inform and train farmers and stakeholders about new practical applications of our research. In addition, the technology, knowledge and research available and enabled by the acquisition of the Gerstel GC/MS system through this grant hasbeen immediately relevant to students and classes at WVU. A first group of graduate students hasreceivedtraining in this new technology which will be an integral part of their thesis projects. In addition, a few undergraduate students have received some training in utilizing the new technology for their independent study and research projects. Moreover, utilization of the new Gerstel GC/MS system has also been included in the curriculum of the PLSC593 - 'Analytical Instrumentation' class as wellas the redesigned curriculum of the WVU Graduate Program in Genetics and Developmental Biology for which a respective proposal has been re-submitted to the NSF Research Traineeship (NRT) program. Changes/Problems:Some delays in the implementation of the proposed objectives were caused by Covid-related restrictions that were still in place in Fall 2021 and in 2022 at WVU. What opportunities for training and professional development has the project provided?1) In 2022 the lab technician Paige Bragg and Dr. Gutensohn (PI) attended a 3-day hands-on training course at the US headquater of Gerstelto learn more about specific features and protocols concerning the new GC/MS system. In 2023Dr. Gutensohn (PI) was invited to a 1-day workshopat the US headquater of Gerstelwhich also included hands-on demonstrations. 2) Other CoPIs and collaborators as well asgraduate students from these labs have been trained in the utilization of the Gerstel GC/MS system and technology (as needed for their respective research projects) by Paigge Bragg, Dr. Gutensohn or Dr. Lynch (who previously had already received training through Gerstel). 3) Dr. Lynch has integrated the use of the Gerstel GC/MS and associated sample collection and preparation technologies into the curriculum of his graduate level PLSC593 class 'Analytical Instrumentation' which he offered in Fall 2022 and Fall 2023. How have the results been disseminated to communities of interest?1) Some results of research projects utilizing the Gerstel GC/MS system and technology have already been communicated to research communities via presentations at scientific conferences includingAnnual Meeting of the Phytochemical Society of North America (PSNA), Annual Meeting of the Midwest Section of the American Society of Plant Biologists (ASPB), Annual Meeting of the Entomological Society of America (ESA). 2) The results of one project, studying the interaction of the invasive plant glossy buckthorn and insects, led by Dr. Yong-Lak Park and Dr. Gutensohn that hadutilizedthe Gerstel GC/MS system and technology have been published as manuscript in 2023 (Greenleaf et al. (2023),Arthropods associated with invasive Frangula alnus (Rosales: Rhamnaceae): Implications for invasive plant and insect management. Insects 14, 913). Several other manuscripts that will include results from analysesutilizing the Gerstel GC/MS system and technology are currently in preparation and will be submitted for publication in respective scientificjournals in the near future. 3) Other results that have been obtained byutilizing the Gerstel GC/MS system and technology have beenincluded as preliminary data in grant proposals that have been submitted to various funding agencies and are currently under review. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Objective 1: The Gerstel GC/MS system was ordered in Fall 2021, delivered and installed in the Analytical Biochemistry Core (ABC) Lab in the Agricultural Sciences Building at West Virginia University in January 2022, and is operational and available to users since March 2022. Objective 2: The lab technician Paige Bragg (newly hired in Fall 2021) as well as Dr. Gutensohn (PI) and Dr. Lynch received a first technical training already during the installation of the Gerstel GC/MS system in the ABC lab at WVU. In August 2022 the lab technician Paige Bragg and Dr. Gutensohn attended a 3-day hands-on training course at the US headquater of Gerstelto learn more about specific features and protocols concerning the new GC/MS system. Dr. Lynch had received this hands-on training at the Gerstel headsquater already previously. Over the last two years Paige Bragg hasreceivedadditional virtual training and technical support by Gersteltechnicians as needed. In 2023 Dr. Gutensohn was re-invited to a one-day workshop at the Gerstel headquater which also included further hands-on technical demonstrations.This initial and follow-up training subsequently allowedthe technician Paige Bragg,Dr. Gutensohn and Dr. Lynchto train CoPIs and other collaborators, as well asgraduate students in their labs in the utilization of the Gerstel GC/MS system and technology as needed for respective research projects. Objective 3: Over the last two years asignificant number of the PI/CoPIs and collaborators have started to implement the use of the Gerstel GC/MS system and technology into ongoing and new research projects. This includes research projects from a number ofdifferent disciplines such as: Plant Science & Biochemistry: analysis of flower and leaf volatiles (Gutensohn), analysis of flavor profiles in hard cider (Gutensohn), analysis of flavor profiles of herbs and microgreens under different storage conditions (Verlinden), influence of climate change scenarios on volatile traits (Waterland), analysis of aromatic amino acid biosynthesis in plants (Lynch) Entomology: chemical communication in insect-plant interactions (Park), chemical communication in insect-fungal interactions (Kijimoto, Kasson), influence of gut microbiota on pheromone production in tsetse flies (Rio) Food & Animal Science: detection of food borne pathogens through volatiles (Jaczynski, Matak),flavor profile of hamderived from pigs under different feeding regimes (Barnes) The growing usage and interest in theGerstel GC/MS system and technologyis alsodemonstrated by the submission ofgrant proposals that contain preliminary data collected by the Gerstel GC/MS system and/or propose to use the Gerstel GC/MS technology: Gutensohn (USDA NIFA, USDA SCRI), Lynch (USDA NIFA ,NSF MCB), Lynch & Pena-Yewtukhiw (NASA Space Biology), Benedito (USDA NIFA),Park & Gutensohn (USDA NIFA), Jaczynski & Matak(USDA NIFA), Barnes (USDA NIFA). Additional grant proposals that areutilizingthe Gerstel GC/MS system/technology are currently in preparation (including the collection of respective preliminary data) and are expected tobe submitted in 2024. Another benchmark for the implementation of the Gerstel GC/MS system is the growingnumber of presentations at scientific conferences as well as of manuscriptsin preparationthat include data collected by utilizing the Gerstel GC/MS system. It is noteworthy that a first paper including datacollected by utilizing the Gerstel GC/MS system has been published in 2023 (Greenleaf J., Holásková I., Rowen E., Gutensohn M., Turcotte R., and Park Y.L. (2023). Arthropods associated with invasive Frangula alnus (Rosales: Rhamnaceae): Implications for invasive plant and insect management. Insects 14, 913). Objective 4: The use of the Gerstel GC/MS and associated sample collection and preparation technologies was integrated into the curriculum of the graduate level PLSC593 class 'Analytical Instrumentation' that was offeredin Fall 2022 and 2023 by Dr. Lynch. In the future this class will be also integrated into the revised curriculum of the Genetics and Developmental Biology Graduate Program at WVU. In this context a group of WVU faculty from the Davis College of Agriculture, the Department of Biology, and the WVU Health Sciences has submitted a proposal (currently under review) to the NSF Graduate Research Traineeship (NRT) program in an effort to redesign the Genetics and Developmental Biology Graduate Program and integrate data sciences. Part of this proposal is to offer a number of hands-on classes to introduce graduate students to highthroughput analytical life science technologies such as those offered by the Gerstel GC/MS system. Likewise, the curriculum committee for the intercollegiate undergraduate Biochemistry program at WVU is currently developing plans for a new 400-level biochemistry class withan associated lab section which will introduce undergraduate students to various analytical techniques including the Gerstel GC/MS system. Moreover, a number of undergraduate students enrolled in independent study, research, and capstone classes have and are currently utilizing theGerstel GC/MS system. Due to delays caused by Covid related restrictions the use of theGerstel GC/MS system has not yet been implemented into activities for middle- and high-school students, however, during a recent FFA event that was hosted by the Davis College at WVU the PI and CoPIs had the opportunity to discuss respective plans with a number of teachers. Objective 5: Our efforts to make the Gerstel GC/MS system and technology available to other users through collaboration with the WVU Shared Research Facilities (SRF) have been delayed due to severalchanges in personnel at the SRF. However, the PI and CoPIs have personally reached out to collaborators and scientistsat WVU and other universities and research institutions to make them aware of the availability of theGerstel GC/MS system and technology at the WVU ABC lab. These efforts have already resulted in the recruitment of new users from WVU (i.e. Dr. Rio, Biology) and Utah State University (Dr. Borghi, Biology).
