Lowbleed,highefficiencyMXT®-1HTSimDistcolumnsoutperformcompetitors (ASTMD6352conditions).
Higherefficiencymeans:
• Greater resolution; analyzemore samples
beforemethod criteriaare reached.
• Assuredmethodperformance.
Lowerbleedmeans:
• Longer column lifetime.
• More stable calibrations.
• Accurateboilingpoint determinations.

• Stableup to450 °C—lowest bleed for longest column lifetime.
• Reliablymeet allASTMD6352,D7169, andD7500 specifications.
• 100%dimethyl polysiloxane phase allows easy comparisons tohistorical data.
Accurate boiling point determination for medium and heavy fractions using GC
simulated distillation requires columns and phase polymers that are robust enough
towithstandhigh temperatureswithout significant degradation.Metal columns are
a better alternative than fused silica, and theMXT®-1HT SimDist columns are the
lowest bleed, highest efficiency columns available, outperforming other metal
columns for criticalmethodparameters.
