HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ OPTI-GUARD™ C18, Biocompatible 1 mm Guard Column
OPTI-GUARD™ sets the standard for low-impact, easy to use pre-column protection.
Thermo Scientific™ Hypercarb™ Drop-in Guard Cartridges
Offer convenience, economy and effective protection for extending column lifetime.
Thermo Scientific™ Hypersil GOLD™ aQ Javelin™ Guard HPLC Columns
Javelin guard columns offer convenient, easy to use protection for analytical HPLC columns
MilliporeSigma™ Supelco™ SUPELCOGEL™ Ca Guard Column, 9 μm Particle Size
For use with SUPELCOGEL™ Ca 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.
Thermo Scientific™ BetaBasic™ 8 Guard Cartridges, 5μm Particle Size
Thermo Scientific™ BetaBasic™ 8 Guard Cartridges are available in limited dimensions. Please contact Customer Service for more details.
Restek™ Pinnacle DB C18 Guard Cartridges, 5 μm
Protects and extends column lifetime.
Thermo Scientific™ GuardGOLD™ Capillary Columns
Protect your analytical column from damage and contamination from nonvolatile materials.
MilliporeSigma™ Supelco™ SUPELCOGEL™ H Guard Column, 9 μm Particle Size
SUPELCOGEL™ H Guard Column is used for the protection of SUPELCOGEL™ Ion Exclusion Columns.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-1 Supelguard Cartridge, 5 μm Particle Size
Due to a mixed retention mechanism, selectivity differences for polar groups are more pronounced than on C8 and C18 columns. C1 columns require 20-30% less organic modifier to provide retention similar to C18 columns.
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™ Astec™ Cellulose DMP Chiral HPLC Guard Kit, 5 μm Particle Size
Guard cartridges to protect Astec™ Cellulose DMP columns
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
Thermo Scientific™ BetaSil™ C18 Javelin™ Guard Columns
Offer convenient, easy to use protection for analytical HPLC columns
MilliporeSigma™ Supelco™ Ascentis™ Express HILIC 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.
