本文对氦质谱检漏仪的反应时间的两种测量方法进行了讨论,指出其中一种方法是错误的。 反应时间和清除时间是氦质谱检漏仪的重要参数之一,通常规定反应时间和清除时间不大于3秒。对仪器经常进行灵敏度校准和反应时间与清除时间的测量是检查仪器是否正常工作的手段之一。就是在 This article discusses two methods for measuring the reaction time of a helium mass spectrometer leak detector, pointing out that one of these methods is wrong. Reaction time and purge time are important parameters for a helium mass spectrometer leak detector, which typically specifies a reaction time and purge time of no more than 3 seconds. Frequent calibration of the instrument and measurement of reaction time and clearance time is one of the means to check if the instrument is working properly. That’s it
