Supplier: Restek

Application specific columns for organochlorine pesticides and herbicides.

Supplier: Restek

Ultra amino columns are made of high-purity, spherical shaped type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications. Aminopropylsilane provides reproducible retention and efficiency for normal-phase or HILIC analysis of simple sugars.

Supplier: Restek

Polar phase general-purpose columns, with Crossbond® Carbowax® polyethylene glycol provides oxidation resistance.

Supplier: Restek

These MXT-2887 columns stationary phase, column dimensions, and film thicknesses have been optimised to exceed the resolution and skewing factor requirements. Siltek-treated stainless steel tubing.

Supplier: Restek

These Siltek treated stainless steel tubing are the most durable high temperature GC columns. High temperature simulated distillation requires a column that can withstand temperatures to 430 °C.

Supplier: Restek

Rt-alumina BOND/Na₂SO₄ columns (fused silica PLOT) are used for Na₂SO₄ deactivation.

Supplier: OMNIFIT

EZ columns are designed to suit the majority of standard laboratory chromatography applications. They are ideal for aqueous systems and compatible with solvents used in common liquid chromatography applications such as protein purification.

Supplier: Restek

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. These columns are ideal for GC-MS applications requiring high sensitivity, including use in ion trap systems.

Rt-Alumina BOND/KCl (fused silica PLOT) are used for KCl deactivation.

Supplier: VICI JOUR RESEARCH

These PEEK columns are designed for naro-bore applications with small amount of samples.

Supplier: UPCHURCH SCIENTIFIC

This narrow-bore short column (2,0×20 mm) creates only a slight pressure increase with virtually no detectable theoretical plate loss when used with a 3 mm int.Ø or larger column.

Supplier: Restek

When extreme pressure shocks and gas flow changes are anticipated there is a possibility for particles to dislodge. In those cases, using particle traps is recommended.

Supplier: Restek

Rtx-DHA (fused silica) columns are crossbond with 100% dimethyl polysiloxane, which is optimised for hydrocarbon analysis.

Supplier: Restek

Trident LC column protection system is available in three levels of protection such as filter only, cartridge only, or filter and cartridge.

Supplier: Restek

Free-Turn architecture lets you change cartridges by hand without breaking inlet/outlet fluid connections, with no tools needed.

Supplier: Restek

Ultra Aqueous C18 is a rugged, reversed phase column with a well balanced retention profile that boasts high reproducibility and compatibility with many mobile phase, even in 100% aqueous conditions.

Supplier: Restek

The Rt®-βDEXsp columns are useful in dual-column configurations, with the Rt-βDEXsm column, for complex enantiomeric separations.

Supplier: Restek

MXT®-1701 Siltek®-treated stainless steel columns are general purpose columns for alcohols, oxygenates, PCB congeners (e.g., Aroclor mixes), and pesticides.

Supplier: Restek

These application-specific columns with proprietary crossbond phases are suitable for organochlorine pesticides and herbicides.

Supplier: Restek

Raptor™ ARC 18 columns are ideal for high-throughput LC-MS/MS applications with minimal sample preparation.

Supplier: Restek

These cartridges are manufactured using high density polypropylene and have polyethylene frits unless otherwise noted. Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic solvents (e.g., polar contaminants from sample extracts).

Supplier: Restek

Viva C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. These general-purpose C8 columns are suitable for a wide range of compounds from acidic through slightly basic.

Supplier: Restek

These Ultra biphenyl columns are made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: Restek

These Viva columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated spherical silica is useful for normal-phase or HILIC separations. These columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.
