HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ SUPELCOSIL™ ABZ+Plus Supelguard Cartridge Kit, 5 μm Particle Size
Offer both high deactivation and unique selectivity.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge, 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™ SRT™-C SEC-2000 Gel Filtration Guard Column, 5 μm Particle Size, Stainless Steel
The bonded phase in SRT™-C SEC columns is more polar than the hydrophilic phase used in SRT™ columns, making SRT™-C columns better suited for the gel filtration analysis of more hydrophobic bioopolymers such as membrane proteins and pegylated antibodies.
MilliporeSigma™ Supelco™ Discovery™ C18 Supelguard™ Guard Cartridge, 5 μm Particle Size
Discovery™ C18 Supelguard™ Guard Cartridges contain a Discovery™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity).
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8-DB Supelguard Cartridge, 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™ C18 Supelguard™ Guard Cartridge Kit, 5 μm Particle Size
Kit includes one cartridge, stand-alone holder, a piece of tubing, 2 nuts and 2 ferrules.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-ABZ Supelguard Cartridge, 5 μm Particle Size
SUPELCOSIL™ LC-ABZ phase has a unique deactivation technology which provides excellent reversed-phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar.
MilliporeSigma™ Supelco™ Ascentis™ Express Phenyl-Hexyl Guard Cartridge, 2 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™ OApak-P Guard Column, 10 μm Particle Size, Sold by MilliporeSigma™ Supelco™
The TSKgel OApak-P Guard Column contains a strong cation exchanger for the removal of dissociated strong acids under the isocratic eluent conditions of 0.75 mM H2SO4. For use in conjunction with TSKgel OApak-A Analytical Columns.
TSKgel™ SuperSW Guard Column, 4 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel Guard Columns are stand-alone and do not require separate holders. For use with 4.6 mm ID TSKgel SuperSW2000 & SuperSW3000 Columns.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-18 Supelguard™ Cartridge Kit, 5 μm Particle Size
A general purpose hydrophobic alkyl phase that is very retentive and gives good peak shape for a wide variety of compounds.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8 Supelguard Cartridge Kit, 5 μm Particle Size
Provides less retention of both polar and non-polar compounds than C18.
TSKgel™ Octadecyl-2PW Guard Column, 5 μm Particle Size, Sold by MilliporeSigma™ Supelco™
The highly cross-linked, polymethacrylate base material of TSKgel Octadecyl-2PW provides excellent stability in high pH buffer systems. It can withstand rigorous cleaning with either acid or base.
MilliporeSigma™ Supelco™ SRT™-C SEC-100 Gel Filtration Guard Column, 5 μm Particle Size, Stainless Steel
The bonded phase in SRT™-C SEC columns is more polar than the hydrophilic phase used in SRT™ columns, making SRT™-C columns better suited for the gel filtration analysis of more hydrophobic bioopolymers such as membrane proteins and pegylated antibodies.
