Dichloromethane gas chromatography
WebNov 26, 2013 · A method for the detection of dichloromethane (DCM) in waste water was developed by using head-space gas chromatography with FID detection. The calibration curve was linear in three orders of magnitude range of DCM levels and the linear correlation coefficient was 0.9995. The limit of detection was 0.004 mg/l and the limit of quantitation … 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.

It can dissolve a huge variety of compounds; whisk them through chromatography columns; and then Rotovap away in a trice. Yet it also has a dark side. DCM has raised health concerns for years: the US Environmental Protection Agency judges it a ‘probable human carcinogen’, for example.

WebTo increase the amount of sample transferred onto the column and reduce the dwell time in the inlet, in order to reduce the potential for reaction between carrier gas and solvent, pulsed-split injection was performed for 20 seconds. Hydrogen served as the carrier gas at a rate of 1.0 mL/min. GC and MSD conditions were as follows:
