Premium Polysiloxane Intuvo GC columns (compatible only with the Intuvo 9000 GC System) are most common stationary phases. Polysiloxanes are stable, robust, and versatile, and are available in the greatest variety. Standard polysiloxanes are characterized by the repeating siloxane backbone. Each silicon atom contains two functional groups; the type and percent level of substitution of the groups distinguish each stationary phase and its properties.
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
Standard Polysiloxane GC Columns: • (5% phenyl) methylpolysiloxane • Nonpolar, general-purpose phase • Bonded, crosslinked, solvent rinsable, and low bleed • High column-to-column reproducibility • Wide range of available dimensions • Available in Fused Silica and UltiMetal • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column • Similar phases: SPB-5, Rtx-5, BP-5, OV-5, 007-2(MPS-5), SE-52, SE-54, XTI-5, PTE-5, ZB-5, AT-5, MDN-5, ZB-5Plus
Standard Polysiloxane GC Columns. DB-210 is particularly designed for optimized for EPA methods 8140 and 609. Bonded and crosslinked, these columns are close equivalents to USP phase G6 and are efficient and solvent rinsable. With effective operation between 45 °C and 240/260 °C, and strict QC testing to the highest industry standards, DB-210 columns provide robust, accurate, and reproducible performance for a wide range of GC/MS applications. Features: • (50%-Trifluoropropyl)-methylpolysiloxane • Excellent for US EPA Methods 8140 and 609 • High polarity, bonded, crosslinked, and solvent rinsable • Exact replacement of HP-210 • Close equivalent to USP Phase G6 • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column
