It works great and no downtime if the bake outs are done at the end of the day.
Rating: 5.0

  • Application Area: 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."

Good value. Need to consistently produce good quality products.
Rating: 4.3

  • Application Area:Perfume, flavonoid, and other fatty acid analysis

"The quality of Restek GC columns used to be good. But recently, the quality has come down. Even for new columns, we see packing materials come out during blank runs. I hope Restek pay attention to quality of GC columns going forward."

I have used this column for 2 years now and it still functions great with no bleeding
Rating: 5.0

  • Application Area:Analyze hydrocarbons upto C44, Terpenes, pesticides, halogenated compounds

"I am very happy with this column as I have not observed any bleeding or any other problems with it. I have obtained very reproducible results. It has been used for a wide range of applications and had no need to change the column."

Very good for our purposes.
Rating: 4.0

  • Application Area:Test medical grade glues

"Medical grade glues are vey hard to analyze and we find that Restek columns are best for our testing processes. Everything is very reproducable. Our only issue is that the glues wear out the columns faster than other products so we would like a more heavy usage column."

These columns make my job easier - don't know what I would do without them.
Rating: 5.0

  • Application Area:GC MS analysis of multiple food analysis QA methods

"I have been working in Industry (Environmental and Food/Beverage) for 32 years and over that time period have tried many manufacturers columns for a multitude of applications. You can't beat this column for separation, ease of quick install, low bleed (non-existent for me applications), longevity - I have had columns that run daily in for over a year without loss of separation and peak quality and sensitivity. They are priced competitively and I have never had to wait for a backorder on these columns. Restek - keep up the great work and thanks for the helpful technical support over the years."

"The columns we purchase from Restek are high quality and produce excellent results with expected reproducibility. They save us time and effort because they are so consistent and the verification process is greatly reduced whenever we change a column."

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.

Column Details:

  • Phase: Crossbond® 1,4-bis(dimethylsiloxy)phenylene dimethyl polysiloxane
  • Length: 10, 15, 20, 30, 40, 60 m
  • ID: 0.10, 0.15, 0.18, 0.25, 0.32, 0.53 mm
  • df: 0.10, 0.15, 0.18, 0.25, 0.36, 0.50, 1.00, 1.50, 2.00 μm
