HPLC Guard Columns and Cartridges
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™ SUPELCOSIL™ Suplex™ pKb-100 Supelguard Cartridge Kit, 5 μm Particle Size
Suplex™ pKb-100 columns feature the same bonded phase functionality as SUPELCOSIL™ LC-ABZ columns.
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™ Discovery™ BIO Wide Pore C18 Supelguard™ Cartridge, 5 μm Particle Size
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately.
MilliporeSigma™ Supelco™ SRT™-C SEC-500 Gel Filtration Guard Column, 5 μm Particle Size, PEEK
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™ Proteomix™ WCX-NP1.7 Weak Cation Exchange Guard Cartridge and Holder, 1.7 μm Particle Size, Stainless Steel
Used for the analysis or small scale purification of positively charged biopolymers including glycoprotein isoforms and mAb variants.
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™ Proteomix™ WCX-NP3 Weak Cation Exchange Guard Cartridge and Holder, 3 μm Particle Size, Stainless Steel
Used for the analysis or small scale purification of positively charged biopolymers including glycoprotein isoforms and mAb variants.
MilliporeSigma™ Supelco™ OPTI-GUARD™ C18 (Violet Label) 1 mm Guard Column
OPTI-GUARD™ sets the standard for low-impact, easy to use pre-column protection.
MilliporeSigma™ Supelco™ BIOshell™ A400 Protein C4 Guard Cartridge, 3.4 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™ SRT™ SEC-1000 Gel Filtration Guard Column, 5 μm Particle Size, Stainless Steel
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™ Proteomix™ SCX-NP5 Strong Cation Exchange Guard Cartridge and Holder, 5 μm Particle Size, Stainless Steel
Used for the analysis or small scale purification of positively charged biopolymers including glycoprotein isoforms and mAb variants.
MilliporeSigma™ Supelco™ SRT™ SEC-2000 Gel Filtration Guard Column, 5 μm Particle Size, Stainless Steel
Sepax SRT™ SEC columns feature a hydrophilic surface layer that effectively shields the highly porous, five micron silica particles from interacting with your sample.
TSKgel™ HHR Guard Column, 5 μm Particle Size, Sold by MilliporeSigma™ Supelco™
All TSKgel HHR-type columns are shipped in THF, which can be exchanged for a broad range of organic solvents.
