PCB标准和标准混合物

美国剑桥同位素实验室（CIL）——PCB 标准和标准混合物，带有标记的同位素PCB标准物质：In response to demand from the analytical commutity,Cambridge Isotope Laboratories has established a program of quality control/quality assurance for the development of"certified"standards for polychlorinated biphenyls(PCB)in both their carbon-13 labelled and native forms.This program is s response to the increased use of labelled surrogate spikes and it also produces "certified"native solutions.Native standard solutions are prepared using good laboratory practices(GLPs).Individual,native,crystalline PCB isomers (98%+purity)are weighed in triplicate on a microbalance calibrated with National Institute of standards and Technology(NIST)class"s"weights,and diluted to working stock solutions in isooctane. Multiple analyses of each of the three solutions in isooctane at specific concentrations are carried out using gas chromatography/mass spectrometry.In order to establish statistical control,the relative standard deviation (RSD)is required to be less than 5%. among the three solutions of each isomer. Further,the RSD within any single solution must be less than5%. when all of the above parameters are met, these solutions are combined and considered one reference native solution.The accuracy of the CIL solutions are verified against independent laboratory formulation. After the solution is verified, a 1:1 mixture of this reference standard and the labelled analog is made and analyzed again by GC/MC. This establishes a true lot analysis for each of the labelled isomers offered by Cambridge Isotope Laboratories.
