Supercritical fluid extraction (SFE) was on-line coupled with supercri
tical fluid chromatography (SFC) for the determination of thiolcarbama
te herbicides in soil matrix. Inert ODS-silica gel packings were used
as a trap column for an interface between SFE and SFC and as an analyt
ical column for the satisfactory separation of extracts. Thiolcarbamat
e herbicides could be extracted satisfactorily from the soil matrix, w
hich had different characteristics. The results indicated that the pro
posed system was useful for the rapid determination of thiolcarbamate
herbicides in soil matrices.
