HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge, 5 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™ 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™ Discovery™ BIO Wide Pore C18 Supelguard™ Cartridge Kit, 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.
MilliporeSigma™ Supelco™ Discovery™ BIO Wide Pore C18 Supelguard™ Cartridge, 3 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.
MilliporeSigma™ Supelco™ Discovery™ C18 Supelguard™ Guard Cartridge Kit, 5 μm Particle Size
Discovery™ C18 Supelguard™ Guard Cartridges Kit contain a Discovery™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity).
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™ BIOshell™ A160 Peptide C18 Guard Cartridge, 2.7 μm Particle Size
BIOshell™ Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of BIOshell™ columns.
MilliporeSigma™ Supelco™ Ascentis™ Express Biphenyl Guard Column, 2.7 μm Particle Size
Ascentis™ Express 90 Å Biphenyl columns can be used for basic, acidic, or neutral compounds with alternate selectivity from C18 and is especially useful for separating peaks that elute early on C18 and other phenyl phases.
MilliporeSigma™ Supelco™ Ascentis™ Express 160 Å Phenyl-Hexyl Guard Cartridge, 2.7 μm Particle Size
The endcapped, phenyl-hexyl bonded phase provides a stable, reversed phase packing with a pore structure and pore size that is optimized for reversed-phase HPLC separations of peptides and polypeptides, using typical acidic mobile phases favored for proteomic applications.
