Chromatography Columns and Cartridges
MilliporeSigma™ Supelco™ SUPELCOSIL™ Suplex™ pKb-100 Supelguard Cartridge, 5 μm Particle Size
Suplex™ pKb-100 columns feature the same bonded phase functionality as SUPELCOSIL™ LC-ABZ columns.
MilliporeSigma™ Supelco™ Ascentis™ RP-Amide Supelguard™ Guard Cartridge, 5 μm Particle Size
Ascentis™ RP-Amide is a new generation ultra low bleed, embedded polar group (EPG) phase that provides orthogonal selectivity and increased resolution for HPLC and LC-MS analysis of polar compounds. The Ascentis™ RP-Amide is the first choice in embedded polar group HPLC phases.
MilliporeSigma™ Supelco™ Ascentis™ Express 90 Å Biphenyl Guard Cartridge, 5 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™ K Guard Column, 9 μm Particle Size
5 cm x 4.6 mm guard column, does not include tubing, nuts or ferrules.
Thermo Scientific™ BetaBasic™ 18 Javelin™ Guard Columns
Offer convenient, easy to use protection for analytical HPLC columns
Ascentis™ Express 90 Å AQ-C18, 5.0 μm HPLC Guard Cartridge, Sold by MilliporeSigma™ Supelco™
The target analytes include acids, bases, and polar analytes.
TSKgel™ Octadecyl-2PW Guard Column, 5 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel Guard Columns are stand-alone and do not require separate holders. For use with 6 mm ID TSKgel Octadecyl-2PW Columns.
MilliporeSigma™ Supelco™ Discovery™ HS F5 Supelguard™ Cartridge Kit, 5 μm Particle Size
The Discovery™ HS F5 bonded phase provides reversed-phase separations that are distinctly different from C18 columns. However, compounds will generally elute within the same retention time window, making most C18 methods easily transferable.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge Kit, 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).
Thermo Scientific™ BetaSil™ Phenyl Guard Cartridges
Thermo Scientific™ BetaSil™ Phenyl Guard Cartridges are available in limited dimensions. Please contact Customer Service for more details.
MilliporeSigma™ Supelco™ Discovery™ BIO Wide Pore C18 Supelguard™ Cartridge Kit, 3 μm Particle Size
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately.
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™ Ascentis™ Express ES-Cyano 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.
MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge, 5 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.
Empore™ Extraction Disk Cartridge, Sold by MilliporeSigma™ Supelco™
Recommended for the extraction of moderately-polar to non-polar analytes from aqueous samples (e.g., biological plasma).
