Dichloromethane gas chromatography

WebThe injection of analytes into a gas chromatography-mass spectrometry (GC-MS) system using dichloromethane (DCM) as solvent led to gradual deterioration of chromatographic signals, with significant tailing and loss of sensitivity for C17+ hydrocarbons. The injector, gas chromatograph and transfer line were excluded as causes. WebDichloromethane (DCM) or methylene chloride is a volatile, colorless liquid with a chloroform-like odor. When methyl chloride or methane reacts with chlorine gas at very …
