Rtx®-VMSColumns
(fusedsilica)
(proprietaryCrossbond®phase)
• Application-specific columns for volatile organic pollutants byGC/MS.
• Complete separationof USEPAMethod8260B compounds in less than10minutes.
• Stable to260 °C.
• Noknown equivalent phases.
Rtx®-VMS columns offer lower bleed, better selectivity, and overall faster analysis for
separating volatile organic compounds, such as those listed inUSEPAMethod 8260B.
The Rtx®-VMS stationary phase is a highly stable polymer that provides outstanding
analysis of volatile compounds, in combination with sensitive ion traps and Agilent
5973mass spectrometers. 0.18 and 0.25mm ID columns allow sample splitting at the
injectionport,eliminating theaddedexpenseandmaintenanceof a jet separator.A0.45
mmor 0.53mm ID column canbedirectly connected to thepurge& trap transfer line
in a system equippedwith a jet separator.
