Researchers at the University of Washington will purchase a new Thermo MAT 253 isotope ratio mass spectrometer to replace a 25 year old model. This instrument replacement is needed because the existing instrument is experiencing an increase in failure frequency and associated down-time. This increase in failure is causing substantial delays (months) in sample analysis, and the existing software is not compatible with unattended analyses, making analyses more labor-intensive. In addition, the laboratory is a heavily used teaching facility that relies on rapid sample analysis for student research projects, which is jeopardized by the existing instrumentation. The new instrument will be able to measure the isotopic composition of noble gases (Ar, Kr, Xe and Ne), which currently cannot be measured by any mass spectrometers in the laboratory, and will be needed for future research projects. Currently there are 14 projects within the College of Ocean and Fishery Sciences (COFS) that rely on isotope ratio measurements in the laboratory. These projects involve seven faculty and nine graduate students within Chemical Oceanography. Last year, twelve (out of 80) undergraduate Oceanography majors worked in the laboratory either for pay, individual research projects, or for class-related research. The laboratory plays a central role in the research and teaching programs within the COFS. Realizing that the successful operation of the laboratory is currently at risk, and the importance of rectifying this situation, the COFS will provide $100K in matching funds for a new mass spectrometer. In terms of broader impacts, this equipment will substantially improve the infrastructure for research and teaching at the University of Washington. The breadth of research and teaching activities within COFS that are impacted by isotope or gas ratio analyses is demonstrated by the significant number of faculty and students that rely on the laboratory. Because of the large number of graduate and undergraduate students that routinely work in the laboratory, the new instrument will be a key teaching instrument within the COFS.

华盛顿大学的研究人员将购买新的Thermo MAT 253同位素比率质谱仪，以取代25年的型号。 由于现有仪器的故障频率和相关的停机时间增加，因此需要更换该仪器。 失败的增加导致样本分析的大幅度延迟（月），现有软件与无人看管的分析不兼容，从而使分析更加富有劳动力。 此外，该实验室是一种大量使用的教学设施，依赖于学生研究项目的快速样本分析，这受到现有仪器的危害。 新仪器将能够测量贵重气体（AR，KR，XE和NE）的同位素组成，目前无法通过实验室中的任何质谱仪来衡量，并且将来需要进行研究项目。目前，海洋与渔业科学学院（COF）依靠实验室中的同位素比测量值。 这些项目涉及化学海洋学中的七名教职员工和九名研究生。 去年，十二名（在80个）本科生专业的大满贯赛在实验室工作，要么是薪水，单个研究项目或与班级有关的研究。 实验室在COF内的研究和教学计划中起着核心作用。 意识到实验室的成功运营目前处于危险之中，并且纠正这种情况的重要性，COF将为新的质谱仪提供10万美元的匹配资金。 就更广泛的影响而言，该设备将大大改善华盛顿大学的研究和教学基础设施。 依靠实验室的大量教师和学生证明了受同位素或气体比分析影响的COF的研究和教学活动的广度。 由于经常在实验室工作的大量研究生和本科生，新工具将是COF中的重要教学工具。
