HPLC Guard Columns and Cartridges
Thermo Scientific™ Hypersil™ BDS C18 Javelin Guard Columns
Offer convenient, easy-to-use protection for analytical HPLC columns
Thermo Scientific™ Hypercarb™ Porous Graphitic Carbon HPLC Columns
Use for enhanced retention of polar compounds and separation of structurally related analytes with stability at pH extremes and high temperature.
TSKgel™ Super-Octyl Guard Cartridge, Sold by MilliporeSigma™ Supelco™
For 2 mm ID TSKgel Super-Octyl columns
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-18-DB Supelguard Cartridge, 5 μm Particle Size
SUPELCOSIL™ LC-18-DB Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits.
TSKgel™ ODS-120A Guard Cartridge, Sold by MilliporeSigma™ Supelco™
for 4.6 mm ID TSKgel ODS-120A columns
Thermo Scientific™ UHPLC Filters
Protects columns without compromising performance.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-SCX Supelguard Cartridge Kit, 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.
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™ Discovery™ HS F5 Supelguard™ Cartridge, 5 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.
TSKgel™ GMHHR-H (20) and (30) HT2 Guard Column, 30 μm Particle Size, Sold by MilliporeSigma™ Supelco™
The TSKgel™ mixed bed columns are packed with particles of different pore sizes that are blended to provide an extended linear calibration curve. Mixed bed columns are used when a broad range of polymer molar masses is expected in the sample.
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).
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.
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.
