Micro gas dilution from PPM to PPB using only one small precise instrument - 2

DESCRIPTION OF THE APPLICATION AND THE TARGET Standard dictates to measure the overall capacity of the photocatalyst in removing the nitrous oxide, NOx, using and air ﬂow containing NO and NO2 (1ppmv) within an average test time of 5,0 h in lighting condition and with a ﬂow rate of 1.5 L/min. The level of exhaust used is about 500 ppbv. Given the low stability and the diﬃculty to ﬁnd gas test cylinder in such low concentrations, we decided to use standard Mass Flow Controller to reduce through mixing ultrapure air at 500 ppbv of NOx tanks as balance with standard cylinders with a...
