Application Specific GC Columns

The J&W DB-624 capillary Gas Chromatography (GC) column is designed for the analysis of volatile organic pollutants by GC and GC/MS. The DB-624 column is recommended for residual solvent analysis by USP Monograph <467>, and Environmental Protection Agency (EPA) methods for volatile organic compounds (VOCs), including 501.3, 502.2, 503.1, 524.2, 601, 602, 8010, 8015, 8020, 8021, 8240, and 8260.

The J&W DB-624, equivalent to USP phase G43, is a mid-polar 6% cyanopropyl/phenyl, 94% polydimethylsiloxane, available in a range of column dimensions. It is bonded, crosslinked, solvent-rinseable, and has a -20 °C to 260 °C temperature range. The DB-624 column is tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency.
