Abstract

The sensitivity to nitrous oxide of the IMI oxygen analyser (Model 3300) has been tested. Even if the manufacturer's checks are performed and the analyser appears to be functioning correctly, the reading given by the IMI oxygen analyser may be seriously affected by the presence of nitrous oxide. There is a wide variation in the sensitivity to N2O between different instruments, and this variation is partly a function of the electrode. The influence of nitrous oxide on a particular meter may be assessed by placing the probe in 100% nitrous oxide and noting the shift of the meter from zero.

摘要

已对IMI氧气分析仪（型号3300）对一氧化二氮的灵敏度进行了测试。即使进行了制造商的检查且分析仪似乎运行正常，但IMI氧气分析仪给出的读数仍可能受到一氧化二氮存在的严重影响。不同仪器对N2O的灵敏度存在很大差异，这种差异部分是电极的函数。一氧化二氮对特定仪表的影响可通过将探头置于100%一氧化二氮中并记录仪表从零位的偏移来评估。
