the sample is heared at 80℃ in a hermetically sealed vial to allow desorption of contained methannol into the gas phase.when equilibrium is reached,a defined part of the gas phase is injected into a gas chromatograph,where methanol is detected with a flame ionisation detector.normally methanol is the only peak in the chromatogram.
