HPLC Guard Columns and Cartridges
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.
MilliporeSigma™ Supelco™ Ascentis™ Express OH5 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™ Ascentis™ Express Peptide ES-C18 Guard Cartridge, 2.7 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™ Ascentis™ Express 90 Å Biphenyl Guard Cartridge, 2 μm Particle Size
Ascentis™ Express 90 Å Biphenyl columns can be used for basic, acidic, or neutral compounds with alternate selectivity from C18 and is especially useful for separating peaks that elute early on C18 and other phenyl phases.
MilliporeSigma™ Supelco™ SUPELCOGEL™ Ca Guard Column, 9 μm Particle Size
For use with SUPELCOGEL™ Ca columns
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-DP Supelguard Cartridge Kit, 5 μm Particle Size
Contains a diphenyl bonded phase, which gives greater selectivity for aromatic groups compared to alkyl-type bonded phases.
MilliporeSigma™ Supelco™ Proteomix™ SCX-NP1.7 Strong Cation Exchange Guard Cartridge and Holder, 1.7 μm Particle Size, Stainless Steel
Used for the analyis or small scale purification of negatively charged biopolymers, such as glycoprotein isoforms, pegylated proteins and oligonucleotide.
BIOshell™ IgG 1000 Å Diphenyl, 2.7 μm HPLC Guard Cartridge, Sold by MilliporeSigma™ Supelco™
Liquid chromatography column based on a new wide-pore
MilliporeSigma™ Supelco™ Unix™ SEC Guard Cartridge with Holder SEC-200, 1.8 μm Particle Size
Provides high stability and negligible non-specific interactions.
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.
Thermo Scientific™ Hypercarb™ Drop-in Guard Cartridges
Offer convenience, economy and effective protection for extending column lifetime.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-SCX Supelguard Cartridge Kit, 5 μm Particle Size
The LC-SCX cation-exchange columns have strongly acidic propylsulfonic acid groups and are used for separating cations. Adjust pH, ionic strength, and organic modifier concentration to control retention and selectivity.
MilliporeSigma™ Supelco™ Zenix™-C SEC-150 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.
TSKgel™ CN-80Ts Guard Cartridge, Sold by MilliporeSigma™ Supelco™
For 4.6 mm ID TSKgel CN-80Ts columns
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Si Supelguard Cartridge, 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.
