Pinnacle II PAH columns are developed specifically for challenging analyses of polycyclic aromatic hydrocarbons (PAHs).

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

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

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: 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

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

General purpose columns for drugs, solvent impurities, pesticides, hydrocarbons, PCB congeners (e.g., Aroclor mixes), essential oils, semivolatiles.

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

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: BEHR

Glass column with GL45 on both ends, GS 950, according to LUA bulletin no. 20, Ø int.: 60,00 mm, Longueur: 320 mm, Capacité: 950 ml

Supplier: Restek

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

Supplier: Restek

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

Supplier: Restek

Type de colonne: Colonne CPG, SilcoSmooth tubing, Ø int.: 2,00 mm, Longueur: 0,30 m, Ø ext.: 3,18 mm

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

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

Supplier: Restek

Application specific columns for organochlorine pesticides and herbicides.

Supplier: Restek

Analyse active samples accurately; ideal for chlorinated pesticide analysis (reduces endrin breakdown to less than 1%)

Supplier: Restek

Viva C18 are monomeric octadecylsilane columns, highly base deactivated wide pore packing that exhibits peak shape for a wide range of compounds from acidic through slightly basic. General purpose column for analyzing large molecules and biomolecules.

Supplier: Restek

This Rtx®-Dioxin column has greater thermal stability than 5% diphenyl phases or high-cyano confirmation columns.

Supplier: Restek

Allure® Organic Acids columns provide enhanced retention and selectivity for polar organic acids, allowing the separation to be performed on a single 30 cm column.

Supplier: Restek

MXT®-Volatiles columns are designed specifically for the analyses of 34 volatile organic pollutants listed in U.S. EPA methods 601, 602, and 624. With these columns, all compounds can be quantified using mass spectrometer or a PID in tandem with an ELCD.

Supplier: Restek

Graphitised carbon black offers unique selectivity and very little adsorption for alcohol analyses. Two types of CarboBlack supports are available, CarboBlack B and CarboBlack C. CarboBlack B support, with its higher surface area, can hold up to a 10% loading of a non silicone liquid phase. CarboBlack C support can hold up to a 1% loading of a non silicone liquid phase.

Supplier: Restek

Non bonded stationary phase packed columns.

Supplier: Restek

These columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated, wide-pore packing exhibits excellent peak shape for a wide range of compounds. Less retention in reversed phase assays than Viva C18 or Viva C8.
