MXT®-1HTSimDistColumn
(Siltek® treatedstainlesssteel)
(nonpolar phases)
• Stableup to450 °C—lowest bleed for longest column lifetime.
• Reliablymeet allASTMD6352 andD7500 specifications.
• 100%dimethyl polysiloxane phase allows easy comparisons tohistorical data.
Accurateboilingpoint determination formedium andheavy fractions usingGC simu-
lateddistillation requires columns andphasepolymers that are robust enough towith-
stand high temperatures without significant degradation. Metal columns are a better
alternative than fused silica, and the newMXT®-1HT SimDist columns are the lowest
bleed, highest efficiency columns available, outperforming other metal columns for
criticalmethodparameters.

MXT®-1SimDist/MXT®-500SimDist
• Application-specific columns inunbreakable Siltek® treated stainless steel tubing
meet all resolution criteria for high temperature simulateddistillation (e.g.,ASTM
MethodD2887Extended).
• MXT®-1HT SimDist andMXT®-1 SimDist phases offer truemethyl silicone
polarity;MXT®-500 SimDist phase is a carborane siloxane polymer.
• Stable to430 °C.
