The world's first ultra-low-bleed 6% cyanopropyl/phenyl, 94% polydimethylsiloxane GC column, for analysis of volatile compounds.

• Designed for the analysis of solvents according to EPA Methods 524, 624, and 8260, as well as USP 467
• VF-1301ms ultra-low-bleed thin-film has a similar selectivity to 624 and is suitable for semivolatile organic solvents, as well as PCBs and pesticides
• Enhanced selectivity for USP 467 eliminates co-elution of benzene and 1,2-dichloroethane
• Mid polarity
• Low bleed
• 0.15 mm Int.Ø. columns available for high-efficiency GC and GC/MS analyses
• Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency
• Performance Summary shipped with each column
• Similar phases: AT-624, SPB-624, Rxi-624 Sil MS, Rtx-624, PE-624, 007-624, 007-502, ZB-624Plus, ZB-624

VF-624ms (along with VF-1301ms) is the world's first ultralow-bleed mid-polar 6% cyanopropyl/phenyl, 94% polydimethylsiloxane GC column. It eliminates co-elution of benzene and 1,2-dichloroethane and is designed to provide more accurate trace analysis of semivolatile organic solvents according to EPA methods 524, 624, and 8260, as well as USP 467.
