HPLC Guard Columns and Cartridges
Thermo Scientific™ BetaSil™ Diol Guard Cartridge
The Thermo Scientific™ BetaSil™ Diol Guard Cartridge is available in limited dimensions. Please contact Customer Service for more details.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge Kit, 5 μm Particle Size
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
MilliporeSigma™ Supelco™ Astec™ CHIROBIOTIC™ V2 Chiral HPLC Guard Column Cartridge, 5 μm Particle Size
Neutral molecules, amides, acids, esters and amines show considerable enantioselectivity on these vancomycin-based CSPs
MilliporeSigma™ Supelco™ OPTI-GUARD™ C18, Biocompatible 1 mm Guard Column
OPTI-GUARD™ sets the standard for low-impact, easy to use pre-column protection.
TSKgel™ Protein C4-300 Guard Cartridge, Sold by MilliporeSigma™ Supelco™
Addition to the extensive line of Reversed Phase columns from Tosoh Bioscience
TSKgel™ SuperMPHZ-H Guard Column, 6 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.
Ascentis™ Express 90 Å AQ-C18, 5.0 μm HPLC Guard Cartridge, Sold by MilliporeSigma™ Supelco™
The target analytes include acids, bases, and polar analytes.
MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge Kit, 5 μm Particle Size
The Discovery™ HS F5 bonded phase provides reversed-phase separations that are distinctly different from C18 columns. However, compounds will generally elute within the same retention time window, making most C18 methods easily transferable.
MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge, 5 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™ Ascentis™ Express Phenyl-Hexyl 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.
TSKgel™ SuperHZ Guard Column, 3 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel™ Guard Columns are stand-alone and do not require separate holders. For use with TSKgel SuperHZ1000-4000 and HZM-N & -M Columns, 3 μm.
MilliporeSigma™ Supelco™ BIOshell™ A160 Peptide CN Guard Cartridge, 2.7 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.
TSKgel™ GMHHR-H(S) HT2 Guard Column, 30 μm Particle Size, Sold by MilliporeSigma™ Supelco™
The TSKgel™ mixed bed columns are packed with particles of different pore sizes that are blended to provide an extended linear calibration curve. Mixed bed columns are used when a broad range of polymer molar masses is expected in the sample.
MilliporeSigma™ Supelco™ Discovery™ BIO Wide Pore C18 Supelguard™ Cartridge Kit, 3 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.
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.
