Great results
Analyze VOCs in air sample
Very effective, the result was realistic and quality of result is the best. Easy to use and operate. Long lasting.
Review Date: 13 Apr 2019 | Restek Corp.
Great product for my research
Analyses of volatile organic compounds
Very effective and was very easy to install and uninstall when I wanted to move the instrument
Review Date: 12 Apr 2019 | Restek Corp.
Works very well for the aim.
Analyse of volatile organic compounds
Great value for money, easy to use and could be install easily.

Great column at good price
2D-GC-MS quantification of PAHs in aerosol samples
This column (like others from Restek) provides good separation, even of more closely eluting species, and is rather durable (lasting up to a year or more, if sample matrix is not too dirty), and all that at a competitive price.
Review Date: 27 Jul 2018 | Restek Corp.
Low bleed and excllent resolution of closely eluting peaks
Analytis of Technical material
Used the method for the new AI technical material content and its byproducts. we were able to see the reporducibility of injection and peak shape even after more than 150 injections.

Restek's former Rtx®-17 columns are now manufactured using new Rxi® column technology--for unsurpassed inertness, ultra-low bleed, guaranteed reproducibility, and unmatched performance!
The new line of fused silica capillary GC columns - Rxi® columns - is now available! These new columns are designed specifically to be the best columns available, for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to outstanding performance, this combination of column characteristics assures Rxi® columns will have long lifetimes. The Restek chemists also have developed a stable, reproducible manufacturing process, so that Rxi® columns will meet your needs every time you install a new column.
What do Rxi® columns mean to you? Three things:
- Ultra-low bleed.
- Exceptional inertness.
- Reproducible performance, column after column.
- General purpose columns for pesticides, herbicides, rosin acids, phthalate esters, triglycerides, sterols.
- Temperature range: 0°C to 320°C.
Don’t Overestimate Cannabidiol During Medical Cannabis Potency Testing by Gas Chromatography
Accurate potency testing of medical cannabis with gas chromatography (GC) depends principally on choosing a column with the right selectivity; otherwise, coelutions between cannabinoids of interest may cause error in potency measurements. Potency testing for medical marijuana is often done using “5-type” GC columns. However, on 5-type columns cannabidiol can coelute with cannabichromene. This application note demonstrates that to identify and report both of these compounds accurately, a GC column with a different stationary phase is needed.
Characterizing Cellular Fatty Acid Methyl Ester Profiles to Identify Bacteria Using Gas Chromatography
Practical, accurate methods for bacterial identification are of great interest in fields ranging from clinical diagnostics to food safety. When paired with highly inert, lowbleed columns of appropriate selectivity, gas chromatography is one of the most efficient analytical separation methods available. The fatty acid methyl ester (FAME) analyses shown here illustrate the potential of GC-TOFMS for distinguishing clinically relevant species and identifying low-level compounds in these complex biological samples.
Rxi® Technology for Accurate Trace-Level Analysis and New EZGC™ Software from Restek
In this video Jaap de Zeeuw discusses two new technologies highlighted by Restek at Pittcon 2013. Jaap tells SelectScience how the exceptional inertness and stability of Restek’s Rxi® columns makes them well suited to accurate trace-level analyses. In addition to discussing some of the other key benefits of Rxi® technology, including retention time stability and longer column life, Jaap describes some of the key applications areas such as pesticide, PAH and solvent analysis. Jaap also introduces EZGC™, Restek’s new software for GC method development. Interview filmed by SelectScience at Pittcon 2013.
New Low Bleed GC Column and Flow Meter
Watch this Restek interview at Pittcon 2010 to find out about new additions to the Rxi® ultra inert, high performance fused silica GC column family. The Rxi® 6-24 Sil MS increases the maximum temperature to 320oC with very low bleed and is applicable to mass spectrometry applications. A new Flow Meter and website launch are also introduced.
