Featured Application: Volatile Amines on Rtx-Volatile Amine - Robust GC Analysis of Volatile Amines on the Rtx-Volatile Amine Column

Restek’s Rtx-Volatile Amine column is specifically designed for GC analysis of volatile amines in challenging matrices. The stable bonded phase is highly retentive and selective for volatile amines to ensure good chromatographic separations and peak shapes. In addition, the column is very robust and able to withstand repeated exposure to harsh sample matrices, such as water.


Analysis of Biodiesel Fatty Acid Methyl Esters (FAME) in Aviation Jet Fuels Using Method IP 585

Accurate analysis of biodiesel FAME in jet fuel is critical for ensuring that contamination levels do not exceed allowable limits. Method IP 585 is commonly used for this analysis and here we perform the method using a Stabilwax column and GC-MS in SIM mode. Method calibration curve criteria were met and good recoveries of the total FAME content in jet fuel were obtained.

Using Alternative Carrier Gases with Accelerated ASTM D2887 Simulated Distillation Analysis

ASTM Method D2887 now allows for alternate carrier gases, so hydrogen or nitrogen can replace helium carrier gas for simulated distillation. Here, we show that with an MXT-1HT SimDist column and Restek’s EZGC online method translator existing methods using helium can be easily converted to either hydrogen or nitrogen carrier gas. Because retention times are preserved with proper method translation, there are minimal changes to peak identification tables which significantly simplifies method validation.


Alternative Carrier Gases for ASTM D7213 Simulated Distillation Analysis

Carrier gas changes for SimDist methods, such as ASTM Method D7213, can be easily implemented in your daily process. Using MXT-1HT SimDist columns and EZGC method translation software, helium-based SimDist methods can be easily translated to alternative carrier gases while maintaining ASTM Method D7213 requirements.


Benefits and Considerations of Converting to Hydrogen Carrier Gas

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


Fingerprinting Crude Oils and Tarballs using Biomarkers and Comprehensive Two-Dimensional Gas Chromatography

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.


Using Micropacked GC Columns for Analyzing Volatiles in Light Hydrocarbon Streams

Most analysts still use traditional packed columns for light hydrocarbon analysis, but many adsorbents are also available in micropacked column formats. Micropacked columns are a good alternative when both efficiency and sample loadability are desired.


Advanced Capillary Column Technology Improves Analysis of Volatile Amines

Volatile amines, such as monomethylamine, diethylamine, and triethylamine, are widely 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 to high column inertness.



燃料流中の硫黄化合物は装置に損傷を与え、BTU値を減少させる可能性があります。 Sulfinertサンプルシリンダーは、ステンレスシリンダーよりもはるかに不活性であり、捕集、輸送、および保管中のサンプルの完全性を保証します。


Extending the Power of Stabilized PLOT Column Technology to Process GC Analyzers

New metal MXT PLOT columns offer greater stability than conventional PLOT columns, making them a better choice for process GC analyzer applications. New bonding techniques result in highly reproducible flow characteristics, improved layer stability, and excellent separation efficiencies.


Analyze ppb Level Sulfur Compounds Using an Rt-XLSulfur Micropacked GC Column or an Rtx-1 Thick Film Capillary GC Column

Trace levels of sulfur compounds are separated and quantified by using an Rtx-1 capillary column or an Rt-XLSulfur micropacked column. The latter column is a specially deactivated porous polymer in Sulfinert-passivated stainless steel tubing.


Rt-XLSulfur Packed GC Column for Analysis of Low-Level Sulfur Compounds in C1-C6 Hydrocarbon Streams

Rt-XLSulfur columns resolve hydrocarbons from sulfur compounds in hydrocarbon process streams and exhibit excellent inertness with low ppbv levels of sulfurs.


Improve Trace Analysis of Acetylene, Propadiene, and Methyl Acetylene Impurities With Higher Sample Capacity Alumina MAPD Columns

Rt-Alumina BOND/MAPD columns offer higher capacity than other MAPD columns and are ideal for analyzing acetylene, propadiene, and methyl acetylene in petroleum gases. Greater capacity improves data accuracy due to better peak symmetry and a wide linear range.


Analysis of Trace Hydrocarbon Impurities in 1,3-Butadiene Using Optimized Rt-Alumina BOND/MAPD PLOT Columns

Impurity analysis of 1,3-butadiene on an Rt-Alumina BOND/MAPD column results in good separation of both light polar impurities (methyl acetylene, propadiene) and 4-vinylcyclohexene, a heavier contaminant that often requires testing on a second column.


GCxGC Analysis of Complex Petroleum Hydrocarbons: Sulfur Speciation in Diesel

Comprehensive 2D GC, also known as GCxGC, is a powerful technique with a great deal of potential for improving separations of complex petroleum and petrochemical samples that contain hundreds—or even thousands—of components. While GCxGC is still considered emerging technology and is used primarily in research and development labs, it has undergone significant growth in the past few years.


New Alumina Column Shows Promise for Analyzing Chlorofluorocarbons

Rt-Alumina BOND/CFC columns provide high retention and high selectivity for volatile halogenated hydrocarbons, without the activity that is usually observed with alumina adsorbents. Chlorofluorocarbon analysis, in particular, can benefit from this new technology.


Stable Sulfur & Mercury Sampling in Refineries - Using Siltek and Sulfinert Surface Treated Components

Refinery and natural gas samples often contain trace amounts of sulfur- and mercury-containing compounds, which can interfere with reactions, poison catalysts in petrochemical processes, and damage equipment. Because these compounds quickly react with stainless steel surfaces, accurate determination of these compounds is impossible when samples are collected and stored in untreated sample cylinders. Restek's Siltek and Sulfinert passivation techniques bond an inert layer into the surface of stainless steel, preventing active compounds from reacting with or adsorbing to the steel.
