MXT®-1HT SimDist Column
(Siltek® treated stainless steel)
(nonpolar phases)
• Stable up to 450 °C—lowest bleed for longest column lifetime.
• Reliably meet all ASTM D6352 and D7500 specifications.
• 100% dimethyl polysiloxane phase allows easy comparisons to historical data.
Accurate boiling point determination for medium and heavy fractions using GC simu-
lated distillation requires columns and phase polymers that are robust enough to with-
stand high temperatures without significant degradation. Metal columns are a better
alternative than fused silica, and the new MXT®-1HT SimDist columns are the lowest
bleed, highest efficiency columns available, outperforming other metal columns for
critical method parameters.
MXT®-1 SimDist Column
(Siltek® treated stainless steel)
(nonpolar phase)
MXT®-1 SimDist/MXT®-500 SimDist
• Application-specific columns in unbreakable Siltek® treated stainless steel tubing
meet all resolution criteria for high temperature simulated distillation (e.g., ASTM
Method D2887 Extended).
• MXT®-1HT SimDist and MXT®-1 SimDist phases offer true methyl silicone
polarity; MXT®-500 SimDist phase is a carborane siloxane polymer.
• Stable to 430 °C.
