Determination of trichloroacetaldehyde,pyridine,and epichlorohydrin in water by gas chromatography
Determination of trichloroacetaldehyde by headspace gas chromatography(ECD),pyridine by headspace gas chromatography(FID)and epichlorohydrin by purge-and-trap gas chromatography(ECD)were verified.Results display that this programme has the advantages of short pre-treatment time,higher sensitivity,environmental friendliness,accura-cy,and strong practicality.Through the interactive use of instrument configuration,three independent indicators can be quickly analyzed to further improve the efficiency of environmental monitoring and analysis work.
