Development of a chloroform reference material for the proficiency testing of hazardous compounds in commercial consumer chemical products under the consumer chemical products and biocide safety management act (K-BPR)

초록

In this study, a chloroform consumer chemical product (CCP) reference material (RM) is successfully developed, with potential to be used in the proficiency testing of hazardous compounds in CCPs for analysis and testing agencies. Validation experiments are rigorously conducted to evaluate whether the RM meets the requirements set by the ISO 13528 and ISO Guide 35, using a reliable GC/MS method for the analysis of chloroform. The obtained calibration plot linearity, limit of detection (LOD), and limit of quantitation (LOQ) are excellent. The developed RM meets the homogeneity and stability requirements; the between-unit (s<inf>bb</inf>) and within-unit (s<inf>wb</inf>) standard deviations are less than 2.5%, and the stability is found to be guaranteed for 50 days. © Korean Society for Mass Spectrometry.
