<p>The invention relates to a gas chromatographic device comprising at least an inlet system, a column and a pressure reducing means, said pressure reducing means being capable of reducing the pressure prevailing at the inlet of said pressure reducing means to a column outlet pressure which is essentially vacuum. Preferably, the inlet pressure of the device is 10 to 1000 kPa and the pressure prevailing at the outlet of said pressure reducing means is 0.00001 to 50 kPa (absolute pressure).</p> |
