Restek's Capillary GC Columns for Simulated Distillation of Petroleum Fractions

This application note describes the method for simulated distillation of petroleum fractions using Restek’s capillary GC columns. Simulated Distillation (Sim Dist) is an analysis which determines the boiling range distribution of petroleum samples using gas chromatography with temperature programming. Different Sim Dist methods are employed depending upon the boiling range of hydrocarbons in the product to be analyzed. Restek’s capillary columns, with crossbonded stationary phases, offer several advantages compared to packed columns, including lower column bleed, shorter conditioning times, shorter analysis times, and longer column lifetimes.
