Standard Polysiloxane GC Columns: • 100% dimethylpolysiloxane (PDMS) • Nonpolar • General purpose phase • Bonded, crosslinked, and solvent rinsable • Separates almost entirely based on boiling points, making this column suitable for a wide range of applications with a broad temperature range • Available in Fused Silica or UltiMetal • Tested against the strictest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column • Similar phases: SPB-1, Rtx-1, BP-1, OV-1, OV-101, 007-1(MS), SP-2100, SE-30, ZB-1, AT-1, ZB-1
Ultra Inert GC Columns. DB-624 UI is optimal for the fast analysis of volatile organic compounds (VOCs) in pharmaceutical, environmental, food, and industrial chemical applications. The unique Ultra Inert deactivation process enhances peak shape, improving signal-to-noise levels and increasing sensitivity for qualitative and quantitative analysis.
Application Specific GC Columns. DB-VRX features unique selectivity, engineered for optimum resolution of volatiles. These low-polarity columns deliver excellent peak shapes and are fully compliant with U.S. EPA methods 502.2, 524.2, and 8260. They are bonded and crosslinked, and require no subambient cooling to resolve the six 'gases'. DB-VRX features an operating temperature range of –20 to 260 °C.
