DV3000 Specificity

The ability to discriminate between VOC’s which are present
The DV3000 gas analyser from Duvas Technologies is able to qualify and quantify up to 13 gases, including BTEX and NOx, simultaneously to low ppb levels without cross interference between species. The technique uses differentials between a reference profile and a sample profile. Every species has its own unique absorption spectrum, like a fingerprint, making it possible to identify each individual species present at its concentration and the DV3000 uses complex algorithms to de-convolute these spectra.
