European Reference Laboratory for Air Pollution (ERLAP)
ERLAP was founded in 1994 to serve as a calibration facility for measurements of particulate matter and gaseous air pollutants in Europe. Inter-laboratory comparisons have been organized yearly or more for 2 decades. As a service of the European Commission, ERLAP provides support independently of national and private interests, which makes it unique in Europe.

Interlaboratory comparisons of OC/EC analysis
The European Reference Laboratory for Air Pollution organises the inter-laboratory comparison for the measurement of total carbon (TC), elemental carbon (EC) and organic carbon (OC) in particulate matter collected on filters.The aim of this exercise is to evaluate the performances of the measurement method (i.e. reproducibility and repeatability) and of individual laboratories (bias and variability).The exercise is based on ambient PM2.5 aerosol samples collected on quartz fiber filters at a regional background site in Ispra, Italy. The precisions of the measurement method is calculated according to the ISO5725-2 and the laboratory performance is determined in terms of z-scores according to the ISO 13528. In addition, for the purpose of harmonizing TC, OC and EC air mass concentrations reported into the EBAS database, quality control measures are calculated for TC, OC and EC determination for each participant.Fabrizia Cavallie-mail: fabrizia.cavalli[at]ec.europa.euphone: +39 0332 785919
