HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge, 3 μm Particle Size
Ascentis™ C18 is an extremely stable and reliable HPLC column that gives symmetric peak shape and excellent retention even for difficult compounds.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8-DB Supelguard Cartridge Kit, 5 μm Particle Size
SUPELCOSIL™ LC-DB phases are specially deactivated for basic compounds. These columns provide less retention, better peak shape, and higher efficiency for organic bases than can be obtained on conventional reversed-phase columns.
TSKgel™ Octadecyl-4PW Guard Cartridge, Sold by MilliporeSigma™ Supelco™
Highly cross-linked polymethacrylate base material of TSKgel Octadecyl-4PW provides excellent stability in high pH buffer systems and can withstand rigorous cleaning with either acid or base.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Diol Supelguard Cartridge Kit, 5 μm Particle Size
LC-Diol columns can be used to separate proteins by gel filtration chromatography.

MilliporeSigma™ Supelco™ Astec™ Cellulose DMP Chiral HPLC Guard Kit, 5 μm Particle Size
Guard cartridges to protect Astec™ Cellulose DMP columns
MilliporeSigma™ Supelco™ Ascentis™ Express F5 Guard Cartridge, 2 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™ 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).
