HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ CHIRALPAK™ CBH HPLC Guard Column, 5 μm Particle Size
CHIRALPAK™ CBH phase has cellobiohydrolase as the chiral selector immobilized on spherical 5 μm silica particles.
Thermo Scientific™ Hypercarb™ Porous Graphitic Carbon HPLC Columns
Use for enhanced retention of polar compounds and separation of structurally related analytes with stability at pH extremes and high temperature.
MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge, 3 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™ SUPELCOSIL™ LC-8 Supelguard Cartridge Kit, 5 μm Particle Size
Provides less retention of both polar and non-polar compounds than C18.
MilliporeSigma™ Supelco™ OPTI-GUARD™ C8 1 mm Guard Column
OPTI-GUARD™ sets the standard for low-impact, easy to use pre-column protection.
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™ SUPELCOSIL™ LC-18-DB Supelguard Cartridge Kit, 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.
MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge, 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™ Chromolith™ CN Guard Cartridges, 5-4.6
Functions in reverse phase (when in RP mode) or normal phase. MilliporeSigma™ Chromolith™ CN Guard Cartridges, 5-4.6 come in 3 pieces with 5mmL x 4.6mmID.
MilliporeSigma™ Supelco™ Ascentis™ Express ES-Cyano 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™ SUPELCOSIL™ LC-Si Supelguard Cartridge Kit, 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.
