| Abstract: | A method for the determination of dimethyl ether in liquefied petroleum gases(LPG) was established by capillary gas chromatography.Dimethyl ether in LPG was absorbed by acetone.After being separated by HP-1 column,the content of dimethyl ether in LPG was determined by hydrogen flame ionization detector(FID) and external standard method.The linearity range was 0.5%-30%(volume ratio).The limit of quantification was 0.2%(volume ratio).The RSD was 2.3%-7.3%(n=6).The accuracy was investigated using liquefied pet... |
