  • Process and apparatus for testing bottles for contamination
    Patent number: 5365771
    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.
