You will probably need to use gas chromatography for the analysis. Here is an example of such an analysis, methane in an aqueous sample matrix:
Note that in that application, one of the analytes was water, so a thermal conductivity detector (TCD) was needed, but for your application, a flame ionization detector (FID) would suffice.
In order to quantitate the methane, you will need a calibration gas standard, available from most gas suppliers (e.g. Air Liquide), which would have a specified level of methane in a carrier gas (e.g., nitrogen).Source(s): Lots of experience analyzing gases by GC.
