Solutions of Polychlorodibenzo-p-dioxins and Polychlorodibenzofurans in n-Nonane (EN1948) ---------英文名称The set consists of 11 ampoules, one of BCR-614S2, BCR-614S4-9 and two of BCR-614S1 and BCR-614S3.The nine solutions of natural and labelled PCDD and PCDF congeners in n-nonane are presented in brown glass ampoules sealed under helium gas. Ampoules S1 to S7 contain about 1 mL solution and ampoule S8 about 0.5mL. Solutions S1-8 are supplied in one set together with a non-certified solution S9 intended to verify performanceof the chromatographic separation system.The solutions BCR 614 S1 to S5 are intended as GC-HRMS calibration solutions and are ready for use. An additional solution S0 is available separately for very low level determinations. To apply solutions BCR 614 S6 to S8 in accordance with the European Standard EN 1948, appropriate dilutions should be prepared following the recommendations given in the latter document. Solution BCR 614 S9 may serve to check the instrumental performance, particularly with regard to the chromatographic separation of the 2,3,7,8-Cl substituted congeners from potential interfering compounds. With the current technology, the separation of all analytes from interfering isomers in environmental samples requires the analysis to be performed on at least two capillary columns with different polarity. More details are given in the certification report of BCR-614 in the chapter on instructions foruse.Certified purity of the individual 12C and 13C labeled PCDD and PCDF congeners used for the preparation of the solutionsCongener Purity (%) Uncertainty (%)2,3,7,8-T4CDD . 96.4. 2.71,2,3,7,8-P5CDD . 97.3. 1.11,2,3,4,7,8-H6CDD . 94.6. 1.91,2,3,6,7,8-H6CDD . 98.2. 0.61,2,3,7,8,9-H6CDD . 97.9. 1.01,2,3,4,6,7,8-H7CDD . 98.1. 0.41,2,3,4,6,7,8,9-O8CDD. 99.8. 0.32,3,7,8-T4CDF. 99.5. 0.41,2,3,7,8-P5CDF. 98.7. 1.12,3,4,7,8-P5CDF. 99.6. 0.51,2,3,4,7,8-H6CDF . 97.8. 0.61,2,3,6,7,8-H6CDF . 99.7. 0.51,2,3,7,8,9-H6CDF . 96.4. 1.12,3,4,6,7,8-H6CDF . 98.4. 0.81,2,3,4,6,7,8-H7CDF . 99.8. 0.31,2,3,4,7,8,9-H7CDF . 98.8. 0.51,2,3,4,6,7,8,9-O8CDF . 99.2. 1.613C-2,3,7,8-T4CDD . 98.6. 0.313C-1,2,3,7,8-P5CDD . 98.6. 0.513C-1,2,3,4,7,8-H6CDD . 99.1. 0.313C-1,2,3,6,7,8-H6CDD . 96.7. 0.513C-1,2,3,7,8,9-H6CDD . 99.1. 0.413C-1,2,3,4,6,7,8-H7CDD . 99.3. 1.313C-1,2,3,4,6,7,8,9-O8CDD . 98.6. 0.213C-2,3,7,8-T4CDF . 99.8. 0.413C-1,2,3,7,8-P5CDF. 99.6. 0.413C-2,3,4,7,8-P5CDF. 99.5. 0.313C-1,2,3,4,7,8-H6CDF. 98.8. 0.313C-1,2,3,6,7,8-H6CDF. 99.5. 0.513C-1,2,3,7,8,9-H6CDF. 98.2. 0.513C-2,3,4,6,7,8-H6CDF. 99.6. 0.413C-1,2,3,4,6,7,8-H7CDF. 99.8. 0.313C-1,2,3,4,7,8,9-H7CDF. 99.3. 0.813C-1,2,3,4,6,7,8,9-O8CDF . 99.6. 0.813C-1,2,3,4-T4CDD . 99.2. 0.3
