Abstract: The invention relates to a gas analysis system comprising, from upstream to downstream: a module (SEP) for separating at least a portion of the species contained in the gas to be analysed, comprising at least one microcapillary column (GC) for gas phase chromatography, and a time-of-flight mass spectrometer (TOFMS) coupled to said separation module, said spectrometer comprising a ion source (MS1, MS2) adapted to ionise at least a portion of said species and to emit a ion beam, and a free-flight zone (MS4) for said ions, said mass spectrometer (TOFMS) being arranged in the volume of at least one substrate and comprising a micro-reflectron (R) arranged between the source (MS1, MS2) and the free-flight zone (MS4), a wall (R1) of said micro-reflectron comprising a layer made from a resistive material designed to be polarised between at least two regions so as to create a continuous electrostatic field gradient in said reflectron.
