Direct nitrogen dioxide (NO2) analyser
Serinus 60 NO2 analyser represents the latest, cutting-edge addition, with Cavity Attenuated Phase Shift (CAPS) spectroscopy technology. This technology allows direct measurement of nitrogen dioxide (NO2), rather than an indirect calculation from a chemiluminescence analyser. No converter, no high vacuum, no ozone, and no chemical reactions are required. Using a modulated blue LED light source, the detector measures the phase shift attributable to the level of NO2 in the measurement cell over an average path length of several kilometres.
