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.
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.
TSKgel GMHHR-M Mixed Bed Columns are packed with rigid, multiple pore size, polymer beads. Mixed bed columns are commonly used for unknown samples and for the analysis of polymers with a broad molecular weight distribution.
TSKgel DNA-NPR Columns are packed with 2.5 μm non-porous, high efficiency, hydrophilic polymer beads which are surface modified with a weak anion exchanger. Binding capacity is low compared to porous columns with the same ligand functionality.
TSKgel G7000HHR Columns are packed with rigid, porous, polymer beads. They are used for the non-aqueous separation of polymers with estimated molecular weights less than 400,000,000 Da.
No. 15 Ace-Thred at top and 2 mm bore, solid-PTFE stopcock-plug (tapered 1:5) at bottom. Supplied with nylon and FETFE™ O-ring for connecting 12.5 to 14 mm O.D. tube to column, and with tubing connector.
Densely bonded, extensively endcapped dimethyloctyl stationary phase of Ascentis™ Express 2 μm C8 provides a stable, reversed-phase packing that can be used for basic, acidic, or neutral compounds.
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 back pressures.
