Abstract

The invention comprises a method for collecting a gas sample wherein a gas is collected in a sample conduit (10) of calibrated volume prior to adsortion on an adsorbent material (104) contained in a sample collection vessel (26). The apparatus of the invention comprises a sample conduit (10), means (20) to connect a source (22) of a gas to be sampled to the sample conduit, means (16) to introduce a carrier gas into said apparatus, and a sample collection vessel (26) comprising a container containing an absorbent material (104) which is capable of absorbing or adsorbing at least a portion of said gas to be sampled. A switchable valve means (34) is provided which, in the sampling mode configuration, connects the sample gas to the gas inlet end (12) of the sample conduit and the gas outlet end (14) of the sample to a vent (24) allowing the gas to be sampled to flow from the sample gas source through the sample conduit and out of the apparatus through the vent. In the loading mode configuration the carrier input (16) is connected to the inlet end (12) of the sample conduit and the gas outlet end (14) of the sample conduit is connected to the sample inlet of the sample collection vessel (26) such that carrier gas may flow through the sample conduit and into the sample collection vessel.
