Study Title | Recovery of internal std in SRM-1957 |
Study Type | Untargeted MS anlaysis |
Study Summary | Validation of XLE quantification using standard reference material. High recovery of [13C] labelled chemicals was obtained for important classes of environmental chemicals (PCB, PBDE, PAH, chlorinated pesticides) in NIST SRM-1957. Recoveries ranged from 110±7% for [13C10]mirex to 91 to 105% for congeners of universally [13C] labeled PCBs, PBDEs and chlorinated pesticides, with only [13C12]p,p’-dichlorodiphenyldichloroethylene (p,p’-DDE) having low recovery of 65±6%. Therefore, the simplified extraction procedure provides an efficient recovery of environment chemicals in an organic phase. |

Chromatography Summary: | Samples were analyzed with three injections using GC-HRMS with a Thermo Scientific Q Exactive GC hybrid quadrupole Orbitrap mass spectrometer with 2 µL per injection. A capillary DB-5MS column (15 m × 0.25 mm × 0.25 µm film thickness) was used with the following temperature program: hold 75 °C for 1 min, 25 °C/min to 180 °C, 6 °C/min to 250 °C, 20 °C/min to 350 °C and hold for 5 min. The flow rate of the helium carrier gas was 1 mL/min. Ion source and transfer line temperatures were 250°C and 280°C, respectively. Data were collected from 3 to 24.37 min with positive electron ionization (EI) mode (+70 eV), scanning from m/z 85.0000 to 850.0000 with a resolution of 60,000. |
