Rt -Silica BOND PLOT columns from Restek are ideal for light hydrocarbon, permanent gas, and CFC
analyses. We individually QC test every column with sensitive C4 probes to ensure consistent column-
to-column selectivity. Our proprietarymanufacturing process practically eliminates particle release,
resulting in highly stable retention times. (PDF - 601kB)

The current helium shortage has severely impacted gas chromatographers who are finding that helium
has become significantlymore expensive and is not always available when needed. This article explores
the benefits and considerations of replacing heliumwith hydrogen carrier gas.

Comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC-
TOFMS) was used to analyze petroleum biomarkers creating unique fingerprints of crude oil samples
and tarballs collected after the Deepwater Horizon oil spill.

Comprehensive Two-Dimensional Gas Chromatography
Most analysts still use traditional packed columns for light hydrocarbon analysis, but many adsorbents
are also available inmicropacked column formats. Micropacked columns are a good alternativewhen
both efficiency and sample loadability are desired.
Using Micropacked GC Columns for Analyzing Volatiles in Light
Hydrocarbon Streams
Volatile amines, such asmonomethylamine, diethylamine, and triethylamine, arewidely used in the
petrochemical industry, but are prone to poor peak shape and difficult to analyze. Low levels of volatile
amines can now be accurately reported using new Rtx -Volatile Amine columns due high column
inertness.
Advanced Capillary Column Technology Improves Analysis of Volatile
Amines
Trace levels of sulfur compounds are separated and quantified by using an Rtx -1 capillary column or
an Rt -XLSulfurmicropacked column. The latter column is a specially deactivated porous polymer in
Sulfinert -passivated stainless steel tubing.
Analyze ppb Level Sulfur Compounds Using an
Rt -XLSulfur Micropacked GC Column or an Rtx -1 Thick Film
Capillary GC Column
Rt®-XLSulfur columns resolve hydrocarbons from sulfur compounds in hydrocarbon process streams,
and exhibit excellent inertness with low ppbv levels of sulfurs.
Rt -XLSulfur Packed GC Column for Analysis of Low-Level Sulfur
Compounds in C1-C6 Hydrocarbon Streams
Restek's PLOT column family is the benchmark for performance! Our innovative bonding process
minimizes particle release, reducing column blockage and protecting instrument parts. More consistent
flowmeans stable retention times in Deans and related flow switching techniques.And outstanding
peak symmetry improves impurity analysis for gases, solvents, and hydrocarbons. (PDF - 2296kB)
