Abstract
An apparatus for preparing a gas sample for analysis includes a separation unit configured to separate the gas sample into one or more component samples. A thermal conductivity detector detects the output of the one or more component sample from the separation unit. At least one component sample is collected in a component sample collection unit having a sample collector. The sample collection unit has an outlet for distributing the at least one component sample from the sample collector for analysis.
