This CAREER award by the Analytical and Surface Chemistry program supports work by Professor Glen Jackson at Ohio University to develop a hand-portable mass spectrometer. The instrument is designed to operate above 1 mbar (0.75 Torr), eliminating the need for expensive, complex pumps. The design includes a robust and flexible ion source that can analyze gas-phase neutrals (such as volatile organic compounds and chemical warfare agents) or ions formed from nonvolatile materials via atmospheric pressure ionization techniques. Resolution exceeding that of portable ion mobility spectrometers (the current instruments of choice for screening protocols at most US airports) is expected.Potential applications include national security, forensics, health, and environmental monitoring. The instrument will also serve as a focus for educational outreach, including demonstrations and hands-on experience for high school students, undergraduate students, and field-scientists through both formal and informal avenues. Students will help disseminate knowledge of the new instrument and its capabilities to the broader scientific community by presenting results at national conferences and publishing the results in peer-reviewed journals.

由分析和表面化学项目颁发的CAREER奖支持俄亥俄大学Glen Jackson教授开发便携式质谱仪的工作。该仪器设计工作在1毫巴（0.75托）以上，不需要昂贵的，复杂的泵。该设计包括一个强大而灵活的离子源，可以分析气相中性（如挥发性有机化合物和化学战剂）或通过大气压电离技术由非挥发性材料形成的离子。预计分辨率将超过便携式离子迁移谱仪（目前大多数美国机场的筛选方案选择的仪器）。潜在的应用包括国家安全、法医、健康和环境监测。该仪器还将作为教育推广的重点，包括通过正式和非正式途径为高中学生、本科生和实地科学家提供演示和实践经验。学生将通过在国家会议上介绍结果并在同行评议的期刊上发表结果，帮助向更广泛的科学界传播新仪器及其能力的知识。
