HPLC Guard Columns and Cartridges
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™ SRT™-C SEC-2000 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™ 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-NP5 Weak 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™ Supelguard™ Guard Cartridge Holder - Direct-Connect
For use with Supelguard cartridge (2 cm L. x 3 to 4.6 mm I.D.)
MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge Kit, 3 μm Particle Size
Ascentis™ C18 is an extremely stable and reliable HPLC column that gives symmetric peak shape and excellent retention even for difficult compounds.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-NH2-NP Supelguard Cartridge, 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™ Ascentis™ Express HILIC 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 Biphenyl Guard Column, 2.7 μm Particle Size
Ascentis™ Express 90 Å Biphenyl columns can be used for basic, acidic, or neutral compounds with alternate selectivity from C18 and is especially useful for separating peaks that elute early on C18 and other phenyl phases.
MilliporeSigma™ Supelco™ SUPELCOGEL™ 8Pb, 8% Crosslinked HPLC Guard Column, 9 μm Particle Size
Offers excellent separation of many common samples.
TSKgel™ Amide-80 Guard Columns, 2 μm Particle Size, Sold by MilliporeSigma™ Supelco™
For use with TSKgel Amide-80 Columns, 5 μm. TSKgel Guard Columns are stand-alone and do not require separate holders.
Thermo Scientific™ Hypersil GOLD™ Javelin™ Guard Columns
Offer convenient, easy to use protection for analytical HPLC 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-Si Supelguard Cartridge, 5 μm Particle Size
A typical mobile phase used with normal-phase silica columns consists of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small percentage of more polar solvent.
