MXT®-2887 columns’ stationary phase, column dimensions, and film thicknesses have
been optimized to exceed the resolution and skewing factor requirements specified in
ASTM Method D2887. Each column is individually tested to guarantee a stable base-
line 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 stain-
less steel tubing, MXT® columns are the most durable high temperature GC columns
available.
