Abstract

A method for preparing a sample for analysis includes separating a gas sample into at least one component sample in a separation unit. The output of the at least one component sample from the separation unit is detected, for example, using a thermal conductivity detector. A hydrocarbon in the component sample is combusted in a combustion unit to generate a combustion product. The at least one component sample is collected in a sample collector and supplied to an analysis unit. In some embodiments, the analysis unit may be used to determine an isotopic ratio of the at least one component sample.
