Ultra Inert (UI) GC Columns
DB-624 Ultra Inert (UI) column is optimal for the fast & accurate analysis of volatile organic compounds (VOCs) in pharmaceutical, environmental, food, and industrial chemical applications by GC and GC/MS. Following from its predecessor, this Ultra Inert version of the industry standard DB-624 is also a mid-polar 6% cyanopropyl/phenyl, 94% polydimethylsiloxane, equivalent to USP phase G43. The unique Ultra Inert deactivation process was developed to enhance peak shape for active volatile compounds, improving signal-to-noise levels and increasing sensitivity for qualitative and quantitative analysis of complex VOC mixtures.
