HPLC Guard Columns and Cartridges
BIOshell™ A160 Peptide Phenyl-Hexyl, 2.7 μm HPLC Guard Cartridge, Sold by MilliporeSigma™ Supelco™
The target analytes include peptides and polypeptides < 20 kDa.
MilliporeSigma™ Supelco™ Zenix™ SEC-150 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™-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™ 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™ Hamilton™ PRP-1 HPLC Guard Cartridge Kit, 10 μ Particle Size
Kit includes 1 holder and 2 cartridges
MilliporeSigma™ Supelco™ Astec™ CHIROBIOTIC™ T Chiral HPLC Guard Column Cartridge, 5 μm Particle Size
CHIROBIOTIC™ T columns utilize teicoplanin as a chiral selector.
Thermo Scientific™ HyPURITY™ C18 HPLC Columns, 3μm Particle Size
Thermo ScientificTM HyPURITYTM C18 HPLC Columns are available in limited dimensions. Please contact Customer Service for more details.
Thermo Scientific™ BetaSil™ C18 Javelin™ Guard Columns
Offer convenient, easy to use protection for analytical HPLC columns
MilliporeSigma™ Supelco™ Ascentis™ Express C8 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.
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™ 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™ Discovery™ BIO Wide Pore C5 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. The 2.1 and 4 mm I.D. cartridges use 21150AST or 59660-U (both stand-alone) or 504254 or 55205 (both integral). The 10 mm I.D. cartridges use 567499-U. The 21.2 mm I.D. cartridges use 581392-U.
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.
TSKgel™ SuperMPHZ-N Guard Column, 3 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Tosoh′s innovative multi-pore technology is now also available in 3, 4 and 6 μm TSKgel™ SuperMultiporeHZ Columns and Guard Columns.
