Haloforms and halogenated aliphatic compounds

Numerous methods based on gas chromatography have been described 

Nicolson and Meresz [515] directly ir ected the drinking water sample into a gas chromatograph eqiripped with a scandium tritide electron capture detector. Glass colitmns (1.2nun x 6nun) packed with Chromosorb 101 (60-80 mesh) were used for the anal) is. 

The detection limits for the trihalogenated compounds are all below the lOpg L level. 

The detection limit for dichloropropane is only 60pg L , and the dichlorobenzenes caimot be detected below 500pg L This analysis is not, therefore, suitable for detecting trace levels of some of the dichloiinated hydrocarbons in water.
