HPLC Guard Columns and Cartridges
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™ Ascentis™ RP-Amide Supelguard™ Guard Cartridge Kit, 5 μm Particle Size
Ascentis™ RP-Amide is a new generation ultra low bleed, embedded polar group (EPG) phase that provides orthogonal selectivity and increased resolution for HPLC and LC-MS analysis of polar compounds. The Ascentis™ RP-Amide is the first choice in embedded polar group HPLC phases.
MilliporeSigma™ Supelco™ Ascentis™ Express C18 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™ apHera™ NH2 HPLC Guard Column, 5 μm Particle Size
For use with apHera™ HPLC columns
MilliporeSigma™ Chromolith™ RP Endcapped HPLC Guard Cartridge Starter Kits
Includes the holder and three guard 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™ Hypersil GOLD™ aQ Javelin™ Guard HPLC Columns
