Analysis of 15+1 priority PAHs in acetonitrile; assessment of instrument calibration
Interlaboratory comparison on PAHs in solvent - assessment of instrument calibration
The aim of this study is to provide to national reference laboratories (NRLs) the possibility to assess their instrument calibration for the analysis of EU priority PAHs in standard solutions.
Participation is restricted to officially nominated national reference laboratories.
Test materials and analytes
Two standard solutions containing the 15+1 EU priority PAHs will be supplied to the participants for analysis. The individual PAHs are at a concentration level that allows single dilution (1:10) and addition of internal standards. The solvent is in both cases acetonitrile. Each ampoule contains approximately 2.5 mL of standard solution.
Please bear in mind that the solutions do not contain any internal standards.
The target analytes are:
|benz[a]anthracene (BaA)||benzo[a]pyrene (BaP)|
|benzo[b]fluoranthene (BbF)||chrysene (CHR)|
|benzo[j]fluoranthene (BjF)||cyclopenta[cd]pyrene (CPP)|
|benzo[k]fluoranthene (BkF)||dibenz[a,h]anthracene (DhA)|
|benzo[c]fluorene (BcL)||dibenzo[a,e]pyrene (DeP)|
|benzo[ghi]perylene (BgP)||dibenzo[a,h]pyrene (DhP)|
|dibenzo[a,i]pyrene (DiP)||dibenzo[a,l]pyrene (DlP)|
|indeno[1,2,3-cd]pyrene (IcP)||5-methylchrysene (5MC)|
General outline of the exercise
The participants are requested to perform triplicate analyses on the samples applying a method of their own choice. The preparation of the two samples (e.g. dilution and addition of internal standards) shall be performed on two different days.
The national reference laboratories are requested to analyse the samples and report the results within three weeks after receipt of samples in their laboratories.
Registration and reporting of results have to be done via the WEB based interface at
