HPLC Guard Columns and Cartridges
Thermo Scientific™ Hypersil GOLD™ aQ Javelin™ Guard HPLC Columns
Javelin guard columns offer convenient, easy to use protection for analytical HPLC columns
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™ 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™ SRT™ SEC-300 Gel Filtration Guard Column, 5 μm Particle Size, PEEK
Sepax SRT™ SEC columns feature a hydrophilic surface layer that effectively shields the highly porous, five micron silica particles from interacting with your sample.
MilliporeSigma™ Supelco™ SUPELCOSIL™ Suplex™ pKb-100 Supelguard Cartridge Kit, 5 μm Particle Size
Suplex™ pKb-100 columns feature the same bonded phase functionality as SUPELCOSIL™ LC-ABZ columns.
MilliporeSigma™ Supelco™ Zenix™-C SEC-100 Gel Filtration Guard Column, 3 μm Particle Size, Stainless Steel
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™ Zenix™ SEC-300 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™ SEC-1000 Gel Filtration Guard Column, 5 μm Particle Size, PEEK
Sepax SRT™ SEC columns feature a hydrophilic surface layer that effectively shields the highly porous, five micron silica particles from interacting with your sample.
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™ 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™ Guard Cartridge Holder for BIOshell™ Guard Column
This Guard Cartridge Holder can be used with 4.6 mm, 3.0 mm and 2.1 mm ID BIOshell™ 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.
