Entech is a leading supplier of
canister based sampling equipment, for the collection of volatile
compounds and analytical instrumentation for measurement of volatile
compounds by GC and GCMS. Our environmental products meet EPA
specifications for methods TO1, TO2, TO3, TO12, TO14 and TO15 for VOC
sampling analysis. |
The analysis of adsorbent tubes can be a nightmare for
analytical laboratories, especially when there is a requirement to get
results on 100% of the tubes tested. Instrument problems, unexpected
analyte loading outside of the GCMS calibrated range, and
cross-contamination make the normal “one-shot” analysis very risky.
Even attempting to recover a “split” fraction of the tube onto another
tube is plagued with problems such as added background, poor leak-free
validation, and compounded incomplete recoveries from yet a second
tube. |
