(Siltek®-treated stainless steel)
(nonpolar phase; Crossbond® dimethyl polysiloxane)
• General-purpose columns for solvent impurities, PCB congeners (e.g., Aroclor
mixes), gases, natural gas odorants, sulfur compounds, essential oils, hydrocarbons,
semivolatiles, pesticides, and oxygenates.
• Temperature range: -60 °C to 430 °C.
• Equivalent to USP G1, G2, G38 phases.
• 4.5

standard coil diameter.
MXT®-1 columns exhibit long lifetime and very low bleed at high operating tempera-
tures. A proprietary synthesis process eliminates residual catalysts that could cause
degradation and increase bleed.
