Abstract

The German legislation has a standard list of minimum requirements to approve new measurement techniques to measure gaseous components. The tests are carried out by an independent laboratory and the test report is evaluated and determined to be accepted or refused by a federal committee. Each gaseous component is tested separately both in the lab and during a three month field test where two indentical systems are installed in the same duct and the readings are compared with extractive reference methods. The final approval states the lowest approved measurement range and limitations to fulfill this measurement range. The Opsis DOAS system was tested by TUV in Colone during the years 1990 to 1994 and have so far been approved to measure NO, NO2, SO2, H2O, NH3, Phenol, Formaldehyde, and Mercury for CEM applications.
