Washington State University (WSU) has received funds from the Major Research Instrumentation Program to support the acquisition of a tunable diode laser optical analyzer (TGA100A), a leaf gas exchange system (LI6400), a ten detector isotope-ratio mass spectrometer, and an isotopic water analyzer (L1102-i). The instrumentation will be incorporated into WSU's Laboratory for Biotechnology and Bioanalysis 2 (LBB2) Stable Isotope Core facility. Through the Center for Environmental Research, Education and Outreach (CEREO) this instrumentation will facilitate research and training in the area of global climate change and ecosystem-atmosphere exchange of carbon, nitrogen and water across the University. The TGA100A and LI6400 will be used to measure the exchange of trace gases between the atmosphere and the biosphere at ecosystem and leaf levels. The focus of the mass spectrometer will be to identify sources of nitrogen pollutants and fertilizers in agricultural and natural environments. The L1102-i will be used to study water movement through plants and soil profiles, and to understand how these processes are affected by changing climate. Additionally, the instrumentation will be incorporated into several graduate and undergraduate courses and will be an integral part of a nitrogen methods workshop developed through a NSF funded Integrative Graduate Education and Research Traineeship (IGERT) grant. An internship through the Stable Isotopes Core facilities will also be available to train underrepresented undergraduate and graduate students from regional Universities on the technical aspects of this instrumentation and to engage high school students in independent research projects.

华盛顿州立大学（WSU）已从主要的研究仪器计划中获得资金，以支持获得可调二极管激光光学分析仪（TGA100A），叶子气体交换系统（LI6400），十个检测器同位素质量光谱仪和一个叶子气体交换系统（LI6400）和同位素水分析仪（L1102-I）。 该仪器将纳入WSU的生物技术和生物分析实验室2（LBB2）稳定的同位素核心设施。 通过环境研究中心，教育和外展（CEREO），该仪器将促进全球气候变化以及整个大学的碳，氮和水的全球气候变化和生态系统 - 大气交换领域的研究和培训。 TGA100A和LI6400将用于测量在生态系统和叶片水平下大气和生物圈之间的微量气体交换。 质谱仪的重点是鉴定农业和自然环境中氮污染物和肥料的来源。 L1102-I将用于研究通过植物和土壤剖面的水运动，并了解这些过程如何受到气候变化的影响。 此外，该仪器将被纳入几个研究生和本科课程中，并将成为通过NSF资助的综合研究生教育和研究培训（IGERT）Grant开发的氮方法研讨会的组成部分。 通过稳定的同位素核心设施的实习也将可以培训来自地区大学技术方面的代表性不足的本科生和研究生，并吸引高中学生参与独立的研究项目。
