Chromatography Columns and Cartridges
MilliporeSigma™ Supelco™ SUPELCOWAX™ 10 Capillary GC Column, df 0.25 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™ Chromolith™ RP Endcapped HPLC Guard Cartridge Starter Kits
Includes the holder and three guard cartridges
MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge, 3 μm Particle Size
The Discovery™ HS F5 bonded phase provides reversed-phase separations that are distinctly different from C18 columns. However, compounds will generally elute within the same retention time window, making most C18 methods easily transferable.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Si Supelguard Cartridge, 5 μm Particle Size
A typical mobile phase used with normal-phase silica columns consists of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small percentage of more polar solvent.
MilliporeSigma™ Supelco™ Ascentis™ Express RP-Amide Guard Cartridge, 2.7 μm Particle Size
Ascentis™ Express Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of Ascentis™ Express columns.
MilliporeSigma™ Supelco™ Ascentis™ Express RP-Amide Guard Cartridge, 5 μm Particle Size
Ascentis™ Express Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of Ascentis™ Express columns.

For use with Supelguard cartridge (2 cm L. x 3 to 4.6 mm I.D.)
TSKgel™ Super-Octyl Guard Cartridge, Sold by MilliporeSigma™ Supelco™
For 2 mm ID TSKgel Super-Octyl columns
TSKgel™ Alpha Guard Column, 13 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Guard Column for use with 7.8 mm ID TSKgel Alpha-2500 through Alpha-M Columns.
MilliporeSigma™ Supelco™ Astec™ CHIROBIOTIC™ V Chiral HPLC Guard Column Cartridge, 5 μm Particle Size
Neutral molecules, amides, acids, esters and amines show considerable enantioselectivity on these vancomycin-based CSPs.
MilliporeSigma™ Supelco™ Discovery™ BIO Wide Pore C5 Supelguard™ Cartridge, 5 μm Particle Size
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately. The 2.1 and 4 mm I.D. cartridges use 21150AST or 59660-U (both stand-alone) or 504254 or 55205 (both integral). The 10 mm I.D. cartridges use 567499-U. The 21.2 mm I.D. cartridges use 581392-U.

MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge, 5 μm Particle Size
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
