摘要

PPROBLEM TO BE SOLVED: To easily, safely and inexpensively analyze a large number of samples in a short time, and to quickly analyzeSP17/SPO, as to a water electrolyzer for water stable isotope ratio measurement and a water stable isotope ratio mass spectrometric analytical method. PSOLUTION: In this electrolyzer for mass spectrometric analysis for a hydrogen stable isotope ratio or an oxygen stable isotope ratio, a fluororesin ion-exchange membrane plated non-electrolytically with platinum, iridium, rhodium or iridium/rhodium alloy is sandwiched between a negative electrode comprising platinum-plated porous titanium and a positive electrode therewith, water is brought into contact with a positive electrode side, a current is applied between the positive electrode and the negative electrode to electrolyze the water, and oxygen gas generated in the positive electrode and hydrogen gas generated in the negative electrode are made to flow into a mass spectrograph. The present invention includes the water stable isotope ratio mass spectrometric analytical method. PCOPYRIGHT: (C)2004,JPO&NCIPI

要解决的问题：对于用于水稳定同位素比测量的水电解槽，在短时间内轻松，安全且廉价地分析大量样品，并快速分析 17 O以及水稳定同位素比质谱分析法。

解决方案：在用于质谱分析的氢稳定同位素比或氧稳定同位素比的电解槽中，非电解镀有铂，铱，铑或铱/铑合金的氟树脂离子交换膜夹在中间由包含镀铂的多孔钛和其正极的负极构成，使水与正极侧接触，在正极和负极之间施加电流以使水电解，并在正极中产生氧气使在负极产生的氢气流入质谱仪。本发明包括水稳定同位素比质谱分析方法。
