For laboratory or mobile field testing where space and versatility are critical, choose the Environmental GC system. Equipped with Method 5030 or 5030/5035 compliant Purge & Trap, PID and FID/DELCD detectors, it will easily generate certification quality data for EPA Methods 8021, 8010, 8015, TO-14, and many others. With the optional Thermal Desorber, you can quickly screen soil or other solid matrices for pesticides, PCBs, diesel, and other semi-volatiles. The standard on-column injection port allows for syringe injection, and a second injector may be installed if desired.

For users who do not need the chlorine/bromine selective DELCD detector, the same configuration minus the DELCD is available as the BTEX GC.

These three chromatograms, displayed in PeakSimple, are from an analysis of Method 8021 standard + gases on a Buck Environmental GC system. Peak identities can be confirmed by comparing the results from the three different detectors. Peaks that often co-elute, such as benzene and carbon tetrachloride, can still be measured since the PID responds only to the benzene, while the DELCD only responds to the carbon tetrachloride.
