DB-17ms
• Virtually equivalent to (50%-Phenyl)-methylpolysiloxane
• 320/340°C upper temperature limit
• Very low bleed mid-polarity column, ideal for GC/MS
• Excellent inertness for active compounds
• Enhanced mass spectral integrity
• Bonded and cross-linked
• Solvent rinsable
• Best column for CLP pesticides
Similar Phases: HP-50+, Rtx-50, VF-17ms, 007-17, SP-2250, SPB-50, BPX-50, SPB-17, AT-50

• Mid/high polarity
• Excellent for separations of cis- and trans-fatty acid methyl esters (FAMEs)
• Low bleed
• Bonded and cross-linked
• Solvent rinsable
• Close equivalent to USP Phase G7
