Abstract

An instrument for analyzing organic chemical compounds is provided. The instrument comprises a gas chromatograph which via a molecule separator is connected to the ion source of a mass spectrometer. The separator consists of a number of series connected evacuating stages, each stage being connected to a vacuum pump. Each stage is provided with an input jet nozzle and a coaxial output nozzle, a slide being insertable between these nozzles in the first stage so as to make it possible to switch off the flow through the separator.
