Columns and cartridges for gas, ion, HPLC, low-pressure LC, and flash chromatography; includes pre-packed and open columns, packing, guard columns and accessories, and other supplies for flash chromatography.
Porous-layer open-tubular (PLOT) columns are a powerful tool used in gas chromatography for analysis of fixed gases, light hydrocarbons and volatile solvents. They are mostly preferred over traditional columns.
Use with high-pressure UHPLC for better separation, speed, and throughput of difficult-to-resolve mixtures of halogenated compounds including pesticides.
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.
Use as a robust, general-purpose column for QC/QA applications. They are high-quality, base-deactivated, fully endcapped, have similar C18 selectivity but slightly less retentive.
Available in a variety of stationary phases that function in normal and/or reverse phase. MilliporeSigma Hibar™ HPLC Columns, 125-4 come with customized packing (please specify packing material) and are 125mmL x 4mmI.D.
TSKgel™ SuperHZM-H Mixed-Bed Columns are packed with rigid, porous, polymer beads each having a varying mean pore diameter. They are used for the non-aqueous separation of organic-soluble polymers with high molecular weights of less than 400,000,000 Da.
TSKgel™ NH2-100 amino columns expand the range of TSKgel™ columns for hydrophilic interaction chromatography (HILIC). Offering a different selectivity from the well known TSKgel™ Amide-80 columns, these novel amino-bonded phase columns stand out by providing much improved chemical stability, a prerequisite for achieving reproducible and reliable results.
The TSKgel™ mixed bed columns are packed with particles of different pore sizes that are blended to provide an extended linear calibration curve. Mixed bed columns are used when a broad range of polymer molar masses is expected in the sample.
