Excellent low bleed column and can be used for multiple applications.
Pesticides analysis by GC-MS/MS
Restek Rxi-5 Sil MS capillary column is very effective for trace level of multiple pesticides analysis with its unique low bleed column (Rxi) helps for detecting trace level pesticides in ppb concentration in food matrices using GC-MS/MS.
Review Date: 23 Jun 2021 | Restek Corp.
Excellent column and very useful when detecting pesticides at the ppb level.
Pesticides analysis
Restek capillary columns are extremely good, with low bleeding at high temperatures and high ramp rates.

Great to use it
In analysis & analytical development
It's really value for money, it doesn't require more conditioning and we use if from last long without any complaint about it & still it gives good performance. we are totally satisfied with this product. It provide reproducible, reliable results and enhance confidation of the user too.

highly inert columns.
Pesticides analysis at PPB level.
I have been using Restek GC columns for the last 5+ years. I have been extensively working on pesticide residue analysis in food matrices. The results I have got are very reproducible and there has not been any interference caused by the columns during the scan and method development. I was able to separate out cyfluthrin, cypermethrin isomeric mixture with proper chromatographic separation and reproducible results. Columns are really very robust and long lasting.

Great resolution of multiple compounds!
Analyze hydrocarbons
High quality and reprodible results. Great resolution of different compounds (PAHs, plaguicides, PCBs) in only 15m!

It works great and no downtime if the bake outs are done at the end of the day.
GC MS analysis of isotopes in water.
Our field is isotopes analysis on the oxygen isotopes in water. After working out a procedure to use this 30 m column in our Scion 456-GC to do water isotope comparisons with a mass spectrometer(Scion SQ); it was found to be consistent and reliable. With each batch of samples isotopic standards are run to determine the ratios of the isotopes and the different samples are analyzed and compared to the standards. By taking care to keep the column clean and regularly baked out, it is still in use after 5 years since we received it.

Rxi® fused silica capillary GC columns were 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.
The Rxi®-5Sil MS stationary phase incorporates phenyl groups in the polymer backbone. This improves thermal stability, reduces bleed, and makes the phase less prone to oxidation. Rxi®-5Sil MS columns are ideal for GC-MS applications requiring high sensitivity, including use in ion trap systems.
Rxi®-5Sil MS (Fused Silica) Columns Features:
- Engineered to be a low-bleed GC-MS column.
- Excellent inertness for active compounds.
- General-purpose columns—ideal for GC-MS analysis of semivolatiles, polycyclic aromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines, organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities, and hydrocarbons.
- Temperature range: -60 °C to 350 °C.
