HPLC Columns and Cartridges
TSKgel™ Low Dead Volume Precolumn Filter with 0.5 μm Stainless Steel Frit, Sold by MilliporeSigma™ Supelco™
Can be used to protect the TSKgel columns. When working with columns that contain smaller than 5 μm particles, Tosoh Bioscience suggests the installation of a pre-column filter in front of the (guard) column to avoid clogging the top frit.
TSKgel™ SCX (Na+) HPLC Column, 5 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Packed with 5 mm porous, spherical particles which are surface modified with a strong (sulfonic acid) cation exchanger in the sodium form. Columns are optimized for the separation and analysis of organic acids, saccharides, and alcohols.
TSKgel™ SCX (H+) HPLC Column, 5 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Packed with 5 μm porous, spherical particles which are surface modified with a strong (sulfonic acid) cation exchanger in the hydrogen. Column is optimized for the separation and analysis of organic acids, saccharides, and alcohols.
MilliporeSigma™ Supelco™ EZSafe™ Chromatography Column with Precision Valve, 300 mm
Low pressure (max. 7 psig) medium wall columns with reservoir. Greaseless PTFE insert with screw-thread attaches flow control valve to column. Precision all-PTFE valve and drip-tip.
MilliporeSigma™ Supelco™ Astec™ Cellulose DMP Chiral HPLC Guard Kit, 5 μm Particle Size
Guard cartridges to protect Astec™ Cellulose DMP columns
MilliporeSigma™ Supelco™ Discovery™ BIO Wide Pore C18 Supelguard™ Cartridge, 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™ SUPELCOSIL™ LC-ABZ HPLC Column, 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™ BIOshell™ A400 Protein C4 HPLC Column, 400 Å, 3.4 μm Particle Size
BIOshell™ 400 Å Protein C4 columns contain 3.4 μm advanced Fused-Core particles with 400 Å pores that are specifically engineered to provide efficient separation of larger proteins.
MilliporeSigma™ Supelco™ Ascentis™ Express ES-Cyano HPLC Column, 5 μm Particle Size
The sterically protected, extensively endcapped diisopropyl-cyanopropylsilane stationary phase of Ascentis™ Express ES-Cyano provides a stable, reversed-phase packing that can be used for basic, acidic, or neutral compounds.
MilliporeSigma™ Supelco™ Ascentis™ Express HILIC HPLC Column, 2.7 μm Particle Size
Ascentis™ Express HPLC columns, through the use of Fused-Core™ particle technology, can provide you with both the high speed and high efficiencies of sub-2 μm particles while maintaining lower backpressures.
MilliporeSigma™ Supelco™ Ascentis™ Express F5 HPLC Column, 5 μm Particle Size
Ascentis™ Express 5 μm F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-Si HPLC Column, 3 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-1 HPLC Column, 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™ BIOshell™ lgG, C4 HPLC Column, 1,000 Å, 2.7 μm Particle Size
BIOshell™ IgG 1,000 Å C4 is a high-speed, high-performance liquid chromatography column based on a new wide-pore (1, 000 Å) Fused-Core™ particle design.
