仅描述了具有整体高真空系统的泄漏检测器，以将质谱仪的传感元件保持在低压下。概述了两个程序，一个用于确定最小可检测泄漏率，另一个用于确定最小可检测浓度比。

Only leak detectors are described which have an integral high vacuum system to maintain the sensing element of the mass spectrometer at a low pressure. Two procedures are outlined, one to determine the minimum detectable leak rate and the other for determination of the minimum detectable concentration ratio.
