Mass balance method for purity assay of phthalic acid esters: development of primary reference materials as traceability sources in the Japan Calibration Service System
23-Mar-2011 | Keiichiro Ishikawa, Nobuyasu Hanari, Yoshitaka Shimizu, Toshihide Ihara, Akira Nomura, Masahiko Numata, Takashi Yari ..., Accreditation and Quality Assurance: Journal for Quality, Comparability and Reliability in Chemical Measurement, 2011
Purity assay of high-purity materials (HPMs) of phthalic acid esters (PAEs) was carried out by means of a mass balance method. In this method, chromatographic methods such as gas chromatography-flame ionization detector (GC-FID) and/or high-performance liquid chromatography (HPLC) in combination ...
