Dichloromethane gas
WebAbstract. Dichloromethane (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 high temperatures (400–500 °C), DCM is produced. DCM is extensively used in numerous industrial settings, e.g., in paint stripping, pharmaceutical and paint ... WebBackground: The main aim of the study was to develop an automated static headspace gas chromatography (SHS-GC) method for determination of dichloromethane (DCM) in ampicillin sodium by using a capillary column. Methods: SHS-GC also known as gas chromatography-headspace is the technique of choice due to its high sensitivity, …
