Abstract
On a distributor head for distributing gas samples removed from bottles requiring inspection to the connections for two mass spectrometers, the feed passageways form alternative paths. These different paths are contained in a replaceable part or a switchable valve arrangement. This allows easy changeover from operation with two mass spectrometers to operation with one mass spectrometer, so facilitating servicing of the mass spectrometers.
