Gas chromatography assembly is linked via heat conductivity detector to a mass spectrometer with valve-regulated input

摘要

A gas chromatography assembly (1) is used in conjunction with a mass spectrometer (2) assembly. A gas chromatography separator (7) discharges to the mass spectrometer via a non-destructive heat conductivity detector (8) that is linked to a signal evaluation unit (11). The signal evaluation unit regulates the operation of the inlet valve (12) to the mass spectrometer (2). An independent claim is included for an operating and analytical process.
