Sample PreparationNIST SRM 1597a was diluted 5x in dichloromethane. Isotope-labeled IS/SS are 20 pg on-column. Samples were aliquoted into amber 2 mL, 9 mm short-cap, screw-thread vials (cat.# 21143) containing glass Big Mouth inserts (cat.# 21782) and sealed with 2.0 mL, 9 mm short-cap, screw-vial closures (cat.# 23842).
NotesThe internal standard and surrogate standard mass on column is 20 pg.
