| Study ID | ST001798 |
| Study Title | SRM1957 validation using GC-XLE (2) |
| Study Type | Untargeted MS anlaysis |
| Study Summary | We evaluated quantification using XLE by testing 68 different chemicals (PCB, PBDEs, chlorinated pesticides) in SRM-1958 using external calibration curves (0.05 to 2 ng/mL) and comparing measured values to the reference concentrations reported for SRM. We identified all 40 PCBs that are reported with a reference mass fraction (including certified values and non-certified estimates) in the range of 46.6 to 490 ng/kg in SRM-1958 certificate of analysis (issue date: 11 October 2018). Quantification without adjustment for recovery was reproducible with 29 PCB qualifications at >70% and 35 PCBs at >65% of the reference levels. Eleven out of 13 PBDE/PBBs and all 17 organochlorine pesticides were identifiable and reproducibly quantified in this experiment. Therefore, XLE provides sufficient recovery to support accurate absolute quantification of a broad range of environmental chemicals. Overall, XLE supported measurement of 68 out of the 70 chemicals that are in the ng/kg range in SRM-1958. |
