Abstract
For testing bottles in particular by mass spectrometric analysis, gas samples are removed simultaneously from several bottles by means of probes. The gas samples are fed in succession and in a predetermined sequence to a mass spectrometer by a distributor unit. In this way, a single mass spectrometer is sufficient for testing a number of bottles thus substantially reducing costs in terms of money, maintenance and calibration time.
