HPLC Guard Columns and Cartridges
MilliporeSigma™ Chromolith™ RP Endcapped HPLC Guard Cartridge Starter Kits
Includes the holder and three guard cartridges
Thermo Scientific™ Hypersil™ BDS C18 Javelin Guard Columns
Offer convenient, easy-to-use protection for analytical HPLC columns
Thermo Scientific™ Hypercarb™ Porous Graphitic Carbon HPLC Columns
Use for enhanced retention of polar compounds and separation of structurally related analytes with stability at pH extremes and high temperature.
MilliporeSigma™ LiChroCART™ Column/Purospher™ STAR NH2 Sorbent HPLC Guard Cartridge
HPLC guard cartridge
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8 Supelguard Cartridge Kit, 5 μm Particle Size
Provides less retention of both polar and non-polar compounds than C18.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-18-DB Supelguard Cartridge, 5 μm Particle Size
SUPELCOSIL™ LC-18-DB Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Si Supelguard Cartridge Kit, 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.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-NH2 Supelguard Cartridge Kit, 5 μm Particle Size
SUPELCOSIL™ LC-NH2 Supelguard™ Cartridges contain a SUPELCOSIL™ 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-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™ SUPELCOSIL™ LC-8 Supelguard Cartridge, 5 μm Particle Size
Provides less retention of both polar and non-polar compounds than C18.
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™ Ascentis™ C18 Supelguard™ Guard Cartridge, 3 μm Particle Size
Ascentis™ C18 is an extremely stable and reliable HPLC column that gives symmetric peak shape and excellent retention even for difficult compounds.
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.
