Restek’s PLOT Column Family — The Benchmark for Performance!

• Innovative bonding process minimizes particle release.
• More consistent flow means stable retention times.
• Outstanding peak symmetry improves impurity analysis.

Alternative Carrier Gases for ASTM D7213 Simulated Distillation Analysis

Introduction
Crude oil consists of thousands of di"erent hydrocarbons that span a very wide volatility range. In order to efficiently produce quality finished products, refineries depend on simulated distillation (SimDist) analyses to characterize the composition of their crude feedstock prior to processing.

Virtually Particle-Free Rt®-Silica BOND Columns
Rt®-Silica BOND Columns
  • Versatile column ideal for analysis of light hydrocarbons, sulfur gases, halocarbons, and carbon dioxide.
  • Individually QC tested with sensitive C4 probes to ensure consistent selectivity.
  • Proprietary manufacturing process practically eliminates particle release, reducing downtime due to obstructed FID jets.
  • Bonded silica stationary phase minimizes impact of water, resulting in reproducible retention times for water-containing samples.
