The effect of column length and film thickness of the primary column Rxi-5Sil MS on the separation performance of SCCP congeners. GC × GC-TOF-MS chromatograms of a mixed SCCP standard solution (C_10-13, containing 55.5% chlorine), acquired using (a) 30 m × 0.25 mm × 0.25 µm, (b) 15 m × 0.25 mm × 0.15 µm, and (c) 30 m × 0.25 mm × 0.15 µm Rxi-5Sil MS columns.
