GC Columns
MilliporeSigma™ Supelco™ Omegawax™ Capillary GC Column, df 0.50 μm
Omegawax™ capillary GC column may be used for herbicide determination using In-tube Solid-phase microextraction (SPME).
MilliporeSigma™ Supelco™ β-DEX™ 225 Capillary GC Column, df 0.25 μm
Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
MilliporeSigma™ Supelco™ SUPELCOWAX™ 10 Capillary GC Column, df 1 μm
Polar column that is suitable for the analyses of solvents, fatty acid methyl esters (FAMEs), food, flavor and fragrance compounds, alcohols, and aromatics.
MilliporeSigma™ Supelco™ SLB™-5ms Capillary GC Column, df 1 μm
Designed for the analysis of environmental analytes (such as semivolatiles, pesticides, PCBs, and herbicides) or anywhere a low bleed non-polar column is required.
Restek™ Rtx™-624 Capillary Columns
Application-specific columns for volatile organic pollutants
Restek™ Rtx™-1 Capillary Columns
Similar in polarity to DB-1 and HP-1
Thermo Scientific™ POROS™ R1 10 μm Column, Stainless Steel, 2.1 x 30 mm, 0.1 mL
Thermo Scientific™ POROS™ Prepacked Reversed-Phase Column. POROS™ R1 is a 4000 angstrom pore size Poly[styrenevinylbenzene] particle, suitable for the reversed-phase separation of biomolecules.
MilliporeSigma™ Supelco™ Nukol™ Capillary GC Column, df 0.25 μm
Useful for the analyses of volatile acidic compounds.
MilliporeSigma™ Supelco™ Metal Packed GC Column (fits Agilent, Configuration A), Phase: 5 Carbowax 20M, Matrix 80/100 Chromosorb W HP Support
An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.
MilliporeSigma™ Supelco™ Glass Packed GC Column (fits Agilent, Configuration A), Phase: 10 OV-17, Matrix 100/120 Chromosorb W HP Support
Use a glass column for applications where high inertness is required, such as for the analysis of active analytes. All glass columns undergo a proprietary high temperature silanization to ensure inertness.
MilliporeSigma™ Supelco™ Metal Packed GC Column (General Configuration), Phase: 0.2 Carbowax 1500, Matrix 60/80 Carbopack C Support
An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.
MilliporeSigma™ Supelco™ Astec™ CHIRALDEX™ B-DA Capillary GC Column, df 0.12 μm
CHIRALDEX™ B-DA requires that analytes possess a minimum of two ring structures, one of which is unsaturated (aromatic) alpha, beta to the stereogenic center. Examples include fluoxetine, methylphenidate and chloropheniramine.
MilliporeSigma™ Supelco™ Astec™ CHIRALDEX™ B-DM Capillary GC Column, df 0.12 μm
Used for enantiomeric separation of ephedrine, pseudoephedrine, chlorinated intermediates and methylamphetamine by gas chromatographic analysis.
MilliporeSigma™ Supelco™ Astec™ CHIRALDEX™ B-TA Capillary GC Column, df 0.12 μm
Exhibits high selectivity for oxygen-containing analytes in the form of alcohols, ketones, acids, aldehydes and lactones.
MilliporeSigma™ Supelco™ Astec™ CHIRALDEX™ G-DP Capillary GC Column, df 0.12 μm
Exhibits high efficiency and resolution at low retention times.
