HPLC Guard Columns and Cartridges
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.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge Kit, 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™ Zenix™ SEC-100 Gel Filtration Guard Column, 3 μm Particle Size, Stainless Steel
Like their 5 micron siblings, 3 micron Zenix™ SEC columns feature a hydrophilic surface layer to prevent the sample from interacting with the underlying silica.
MilliporeSigma™ Supelco™ SRT™ SEC-300 Gel Filtration Guard Column, 5 μm Particle Size, PEEK
Sepax SRT™ SEC columns feature a hydrophilic surface layer that effectively shields the highly porous, five micron silica particles from interacting with your sample.
MilliporeSigma™ Supelco™ Ascentis™ Express C18 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.
Thermo Scientific™ BetaSil™ C18 Javelin™ Guard Columns
Offer convenient, easy to use protection for analytical HPLC columns
MilliporeSigma™ Supelco™ Ascentis™ Express HILIC 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™ Guard Cartridge Holder for BIOshell™ Guard Column
This Guard Cartridge Holder can be used with 4.6 mm, 3.0 mm and 2.1 mm ID BIOshell™ columns.
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.
MilliporeSigma™ Supelco™ Astec™ CHIROBIOTIC™ T Chiral HPLC Guard Column Cartridge, 5 μm Particle Size
CHIROBIOTIC™ T columns utilize teicoplanin as a chiral selector.
Holder for 21.5 mm I.D. TSKgel™ Guard Cartridges, Sold by MilliporeSigma™ Supelco™
Holder for guard cartridges, HPLC: suitable
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™ Zenix™-C SEC-300 Gel Filtration Guard Column, 3 μm Particle Size, PEEK
The bonded phase in Zenix™-C SEC columns is more polar than the hydrophilic phase used in Zenix™ columns, making Zenix™-C columns better suited for the gel filtration analysis of more hydrophobic bioopolymers such as membrane proteins and pegylated antibodies.
MilliporeSigma™ Supelco™ Zenix™ SEC-300 Gel Filtration Guard Column, 3 μm Particle Size, Stainless Steel
Like their 5 micron siblings, 3 micron Zenix™ SEC columns feature a hydrophilic surface layer to prevent the sample from interacting with the underlying silica.
