Abstract: | A determination method with the switch valve and gas chromatography mass spectrometry was introduced. This method can determine trace methanol, dimethyl ether and methyl tert-butyl ether in light hydrocarbon. The test results show that the method is sample and its applicability is wide, and the analysis results are accurate, it can provide a reference for ethylene raw material quality monitoring. |
