GC/MS and Headspace facility operating conditions

Headspace oven temperature condtion Headspace purge condition GC/MS oven condition GC column condition MS injection temperature and the sample split condition
Oven (loop + transferline): 35℃ 1. A vacuum vial (50 mL in capacity) was filled with the He gas
2. The vial was vacuumed again and 5 mL of groundwater sample was injected into the vial (10 V%) and purge
Inlet temperature 50℃; initial oven temperature 30℃; temperature increase (30 → 40 at 0.4℃/min; 40 → 200 (hold 5min) → post run 220℃ (for 3 min) VOCOL TM (SUPELCO) FUSED SILICA capillary Column (60 m × 250 μm × 1.5 μm film thickness) Max temperature at the injection port: 250℃ and the 1: 10 split of 1 μl sample
