There is a compelling need for a modern isotope-ratio mass spectrometer to facilitate a range of innovative studies of chemical and biochemical processes. Mass spectrometers operated with a thin permeable membrane over a vacuum inlet allow small gas molecules to be continuously monitored inside specific gas or liquid phase sample chambers. The proposed instrumentation will enable simultaneous and highly sensitive measurement of 10 different isotopic species and the capability for detection of hydrogen. This equipment will provide the many researchers and students with opportunities to determine isotopic signatures of isolated chemical reactions through to complex biochemical systems of whole living cells.

迫切需要一种现代同位素比质谱仪，以促进化学和生物化学过程的一系列创新研究。 质谱仪在真空入口上方使用薄渗透膜，可以在特定的气相或液相样品室中连续监测小气体分子。 拟议的仪器将能够同时和高灵敏度测量10种不同的同位素种类和检测氢的能力。该设备将为许多研究人员和学生提供机会，以确定整个活细胞的复杂生化系统的孤立化学反应的同位素特征。
