Appl icat ion-Speci f ic Columns
MXT®-65TG Columns
(Siltek® treated stainless steel)
(high polarity phase; Crossbond® 65% diphenyl/35% dimethyl polysiloxane)
• Application-specific columns, specially tested for triglycerides.
• Stable to 370 °C.
The MXT®-65TG phase resolves triglycerides by degree of unsaturation as well as by
carbon number. Because of the chemistry required to achieve 370 °C thermal stability,
an MXT®-65TG column should not be used for analyses of compounds that contain
active oxygenated groups.
MXT®-2887 Column
(Siltek® treated stainless steel)
(nonpolar phase; Crossbond® 100% dimethyl polysiloxane—for simulated distillation)
• Application-specific columns for simulated distillation.
• Stable to 400 °C.
MXT®-2887 columns’ stationary phase, column dimensions, and film thickness have
been optimized to exceed the resolution and skewing factor requirements currently
specified in ASTM method D2887. Each column is individually tested to guarantee a
stable baseline with low bleed and reproducible retention times. The Crossbond®
methyl silicone stationary phase has increased stability compared to packed columns,
ensuring stable baselines and shorter conditioning times. Manufactured from Siltek®-
treated stainless steel tubing, MXT® columns are the most durable high temperature
GC columns available.

MXT®-Biodiesel TG Columns
(Siltek® treated stainless steel)
• Fast analysis times and sharp mono-, di-, and triglyceride peaks.
• Stable at 430 °C for reliable, consistent performance.
• Integra-Gap® built-in retention gap on 0.53 mm ID column eliminates column
coupling completely.
