Low bleed, high efficiency MXT®-1HT SimDist columns outperform competitors (ASTM D6352 conditions).
Higher efficiency means:
•
Greater resolution; analyze more samples
before method criteria are reached.
•
Assured method performance.
Lower bleed means:
•
Longer column lifetime.
•
More stable calibrations.
•
Accurate boiling point determinations.
RESTEK ADVANTAGE:
Longer column lifetime and
more accurate data!
RESTEK ADVANTAGE:
Run more samples within method
specifications!

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, D7169, and D7500 specifications.
• 100% dimethyl polysiloxane phase allows easy comparisons to historical data.
Accurate boiling point determination for medium and heavy fractions using GC
simulated distillation requires columns and phase polymers that are robust enough
to withstand high temperatures without significant degradation. Metal columns are
a better alternative than fused silica, and the MXT®-1HT SimDist columns are the
lowest bleed, highest efficiency columns available, outperforming other metal
columns for critical method parameters.
