Selective water removal in purge/gc (gas chromatograph) analysis of volatile aromatics in aqueous samples

Technical Report ·
OSTI ID:6843387

A gas-chromatographic method for volatile aromatics in which an aqueous sample is purged directly to a cryogenically cooled, fused-silica column uses a Nafion tube drier between the purge vessel and GC column to selectively remove water from the analyte-containing purge stream. Volatile aromatics are focused on the cold capillary column with subsequent oven temperature programming for GC analysis. Examples of the technique have been presented on a 5.3 mm, DB-5 column.
