Abstract

In order to determine leakage on a device, which contains gas that can be condensed, an adsorbent is used through which ambient gas of the object is conducted. The adsorbed gas is desorbed by means of actuating an excitation device and fed to a gas sensor containing a mass spectrometer. In this way, minute amounts of leaking gas can be determined by means of accumulation. The method is in particular suited for use in the serial production of refrigeration machines.
