Environmental and BTEX GC Systems - SRI Instruments
The DELCD chromatogram is shown
at left in more detail, with the peaks
labeled for identification. 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 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 to the left 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 Purge & Trap system with
its dual trap technology.
