This article is discussed for the content determination of methanol in Chinese Spirits by gas chromatography using the spirits special capillary column. It includes direct injection, processing temperature rising, using flame ionization ditector(FID) and quantification by external standard method. The results show that, based on the gas chromatography method using the spirits special capillary column and by direct injection, processing temperature rising, it has higher accuracy, fine separability, good precision, less time of analysis and more reliable results.
