    摘要: The present invention relates to a Sampling Module (1) comprising a pump (7) to maintain a constant flow Q, a cold trap (8), a flow regulator (9), a concentration device (14) of the gas sample. Said concentration device (14) includes: a six-way pneumatically actuated valve (10) which allows both to send gas to the cryogenic device (11), and to inject the pre-chilled and post-heated gas into a Gas Chromatograph (2); a cryogenic device (11) to reduce the liquid fractions of water and heavy hydrocarbons and to concentrate the gas sample; a cold trap (12) before the analytical system; a heater (13). The Sampling Module (1) is included into a device whose aim is to analyse mixtures of methane, hydrocarbon compounds Cn with n = 2 - 6 and benzene - toluene - xylene BTX and their single compounds, either with air or without air, and which comprises a Gas Chromatograph (2), an oven (3) or a Pyrolysis device (6), an interface (4) and a High Resolution Mass Spectrometer (5).
