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-NH2 Supelguard Cartridge Kit, 5 μm Particle Size
SUPELCOSIL™ LC-NH2 Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity).
MilliporeSigma™ Supelco™ Discovery™ C8 Supelguard™ Guard Cartridge Kit, 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™ PW-Type Guard Column, 13 μm Particle Size, Sold by MilliporeSigma™ Supelco™
For use with TSKgel™ Columns, shipped in water.
MilliporeSigma™ Supelco™ SRT™ SEC-1000 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 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™ SRT™-C SEC-300 Gel Filtration Guard Column, 5 μm Particle Size, Stainless Steel
The bonded phase in SRT™-C SEC columns is more polar than the hydrophilic phase used in SRT™ columns, making SRT™-C columns better suited for the gel filtration analysis of more hydrophobic bioopolymers such as membrane proteins and pegylated antibodies.
MilliporeSigma™ Supelco™ CHIRALPAK™ CBH HPLC Guard Column, 5 μm Particle Size
CHIRALPAK™ CBH phase has cellobiohydrolase as the chiral selector immobilized on spherical 5 μm silica particles.
BIOshell™ A160 Peptide Phenyl-Hexyl, 2.7 μm HPLC Guard Cartridge, Sold by MilliporeSigma™ Supelco™
The target analytes include peptides and polypeptides < 20 kDa.
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.
MilliporeSigma™ Supelco™ SUPELCOSIL™ ABZ+Plus Supelguard Cartridge, 5 μm Particle Size
Offer both high deactivation and unique selectivity.
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™ 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™ Astec™ Cellulose DMP Chiral HPLC Guard Kit, 5 μm Particle Size
Guard cartridges to protect Astec™ Cellulose DMP 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.
