CERTIFICATION REPORT The certification of the purity of three PAHs, benzo[a]pyrene (ERM-AC051), indeno[1,2,3-cd]pyrene (ERM-AC053) and 6-methylchrysene (ERM-AC082)
This report describes the production of ERM-AC051, benzo[a]pyrene, ERM-AC053, indeno[1,2,3-cd]pyrene and ERM-AC082, 6-methylchrysene, which are pure materials certified for their purity. This material was produced following ISO Guide 34:2009 and is certified in accordance with ISO Guide 35:2017.
The materials were custom synthesized, purified and filled into glass vials.
Between unit-homogeneity was quantified and stability during dispatch and storage were assessed in accordance with ISO Guide 35:2017.
The material was characterised by applying different methods (HPLC, GC, DSC, qNMR, ICP-MS) in different laboratories of demonstrated competence and adhering to ISO/IEC 17025.
Uncertainties of the certified values were calculated in accordance with the Guide to the Expression of Uncertainty in Measurement (GUM) and include uncertainties related to possible inhomogeneity, instability and characterisation.
The main purpose of the material is for preparation of calibrant solutions. As any reference material, it can also be used for control charts or validation studies.
The CRMs are available in amber glass vials containing at least 25 mg powder which were sealed. The minimum amount of sample to be used is 1 mg.
