Description:
A gas chromatographic method was developed and evaluated in a single laboratory for the determination of several groups of pollutants. he method specifies the use of an injection tee leading to two dissimilar fused-silica open-tubular columns connected to two identical detectors. his approach, when compared to packed columns, results in improved resolution, increased sensitivity, and faster (by a factor of two) analyses. he six groups of target analytes are: henols (Method 8040), organochlorine pesticides (Method 8080/8081), nitroaromatics (Method 8090), haloethers (Method 8110), chlorinated hydrocarbons (Method 8120) and organophosphorous pesticides (Method 8140/8141).
