Primary Reference Material PRM a reference material certified with (a) primary method(s). In practice such materials are mainly pure substances, manufactured materials, rarely matrix materials as already explained above. PRMs of matrix materials are very limited in number. NIST has available some CRMs certified with thermal ionisation-isotope dilution mass spectrometry (TMDMS) which has been classified by the Comite Consultatif sur la Quantite de Matiere (CCQM) of BIPM as primary method. PRMs also exist for gas analysis. The Netherlands Meet Instituut (NMI) in Delft, The Netherlands has available several primary gas RMs prepared by gravimetry... [Pg.60]
