Purge and Trap - SRI Instruments
The DELCD chromatogram is shown below in more detail. The DELCD is completely selective for compounds
containing chlorine and/or bromine. Other analytes do not respond at all, even at very high levels. The DELCD
actually operates on the FID's exhaust gases; therefore, all contaminants are pre-combusted by the FID to CO
2
and H
2
O.
The first few peaks in the 8021 standard, including vinyl chloride, are of special interest to many analysts. The
chromatogram on the right shows the expanded detail of the first few peaks in the analysis (the VOC gases). Note
the exceptionally good resolution and peak shape delivered by the SRI system with its dual trap technology.
