HPLC Guard Columns and Cartridges
TSKgel™ UltraSW Aggregate Guard Column, 3 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ UltraSW Aggregate columns have a slightly larger pore size and smaller (3 μm) particle size than the industry-leading TSKgel™ G3000SWXL (5 μm) and SuperSW3000 (4 μm) columns. These 30 cm x 7.8 mm I.D. silica-based, stainless steel columns offer reduced lot-to-lot variation, long column life, reduction of unspecified adsorption, and superior recovery of aggregates.
MilliporeSigma™ Supelco™ Supelguard™ Guard Cartridge Holder - Stand-Alone (Swivel-type)
For use with Supelguard cartridges (2 cm L. x 2 to 4.6 mm I.D.)
MilliporeSigma™ Supelco™ Discovery™ BIO Wide Pore C5 Supelguard™ Cartridge Kit, 3 μm Particle Size
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules.
MilliporeSigma™ Supelco™ SUPELCOSIL™ Suplex™ pKb-100 Supelguard Cartridge, 5 μm Particle Size
Suplex™ pKb-100 columns feature the same bonded phase functionality as SUPELCOSIL™ LC-ABZ columns.
MilliporeSigma™ Chromolith™ HighResolution RP-18 Endcapped HPLC Guard Cartridge
For prolonging the lifespan of Chromolith™ analytical columns
MilliporeSigma™ Supelco™ Ascentis™ Express 90 Å Biphenyl Guard Cartridge, 5 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™ BIOshell™ A160 Peptide C18 Guard Cartridge, 4.7 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™ Discovery™ C8 Supelguard™ Guard Cartridge, 5 μm Particle Size
Discovery™ C8 HPLC column has been used in the separation of fluoroquinolone antibiotics in tablets using reversed-phase high-performance liquid chromatography (RP-HPLC).
TSKgel™ SuperMP(PW)-N Guard Column, 5 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ SuperMultiporePW columns and guard columns can be used for water-soluble polymer analysis.
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.
MilliporeSigma™ Supelco™ Ascentis™™ Express RP-Amide Guard Cartridge, 2 μm Particle Size
The one-step bonded, end-capped, amide-based polar-embedded stationary phase of Ascentis™ Express 2 μm RP-Amide provides, a stable, reversed phase packing with decreased hydrophobic character. Ascentis™ Express 2 μm RP-Amide can be used for basic, acidic, or neutral compounds with orthogonal selectivity from C18 or C8.
TSKgel™ SuperH Guard Column, 3 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Guard Column for use with 6 mm ID TSKgel™ SuperH5000-7000;HM-L;-N;-M;-H Columns, 3 μm.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-SCX Supelguard Cartridge, 5 μm Particle Size
The LC-SCX cation-exchange columns have strongly acidic propylsulfonic acid groups and are used for separating cations. Adjust pH, ionic strength, and organic modifier concentration to control retention and selectivity.
