HPLC Guard Columns and Cartridges
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™ SUPELCOGEL™ 8H, 8% Crosslinked HPLC Guard Column, 9 μm Particle Size
Offers excellent separation of many common samples.
MilliporeSigma™ Supelco™ SUPELCOGEL™ 8Ca, 8% Crosslinked HPLC Guard Column, 9 μm Particle Size
This guard column does not include tubing, nuts or ferrules. Please order them separately.
MilliporeSigma™ Supelco™ Astec™ Cellulose DMP Chiral HPLC Guard Kit, 5 μm Particle Size
Guard cartridges to protect Astec™ Cellulose DMP columns
MilliporeSigma™ Supelco™ Proteomix™ WAX-NP5 Weak Anion 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.
TSKgel™ PWXL Type Guard Column, 12 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ Guard Columns are stand-alone and do not require separate holders. For use with 7.8 mm ID G2500PWxl-GMPWxl Columns, 12 μm.
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™ 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™ 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™ 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™ Hypersil GOLD™ Javelin™ Guard Columns
Offer convenient, easy to use protection for analytical HPLC columns
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™ Proteomix™ WCX-NP10 Weak Cation Exchange Guard Cartridge and Holder, 10 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™ Astec™ CHIROBIOTIC™ T Chiral HPLC Guard Column Cartridge, 5 μm Particle Size
CHIROBIOTIC™ T columns utilize teicoplanin as a chiral selector.
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.
