PM10/PM2.5 comparison exercise in Oslo, Norway. Study in 2015-2016 and 2018.

The purpose of the comparison was to test for equivalence and establish calibration functions for automatic PM-analysers commonly used in Norway. The reference laboratory performed a field test at three different locations in Oslo during summer and winter conditions in the periods September 2015 to July 2016 and February to March 2018. Participating analysers were Palas Fidas 200, Grimm EDM 180, TEI TEOM 1405 DF, TEI FH 62 I-R, and R&P TEOM 1400AB.

The report proposes a system to carry out ongoing verification of equivalence in the Norwegian monitoring network and how to calibrate analyser data.
