MilliporeSigma™ Supelco™ Ascentis™ Express C18 Micron 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™ SUPELCOGEL™ K Guard Column, 9 μm Particle Size
5 cm x 4.6 mm guard column, does not include tubing, nuts or ferrules.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-1 Supelguard Cartridge, 5 μm Particle Size
Due to a mixed retention mechanism, selectivity differences for polar groups are more pronounced than on C8 and C18 columns. C1 columns require 20-30% less organic modifier to provide retention similar to C18 columns.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-DP Supelguard Cartridge Kit, 5 μm Particle Size
Contains a diphenyl bonded phase, which gives greater selectivity for aromatic groups compared to alkyl-type bonded phases.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-DP Supelguard Cartridge, 5 μm Particle Size
Contains a diphenyl bonded phase, which gives greater selectivity for aromatic groups compared to alkyl-type bonded phases.
MilliporeSigma™ Supelco™ Ascentis™ Express 90 Å Biphenyl Guard Cartridge, 2 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.
TSKgel™ ODS-80Ts Guard Cartridge, Sold by MilliporeSigma™ Supelco™
For TSKgel ODS-80Ts & ODS-80Ts QA columns
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.
