Product Category Description:

Suitable for high performance separation of acidic, basic, nonpolar, and metal chelating compounds. Ideal as a first line routine column in the laboratory.

Chromolith column speed comes from a highly porous monolithic silica gel rod clad to the column shell, which allows for high flow rates over a very large surface area. Superior, reproducible separations occur in less time than with packed-particle columns.

CapRod* capillary columns can achieve separations at 1 to 3µL/min., rather than 200 to 400nL/min. for conventional media on a standard nano-LC capillary. Flash and SpeedROD columns are ideal for high-speed separations of simple mixtures. Ideal for use in research laboratories, especially those specializing in combinatorial chemistry.

Performance columns provide rapid, high-quality separation of complex mixtures. The Performance validation kit is ideal for use in quality control or validation laboratories. Kit contains three HPLC columns, each derived from a different batch in order to compare the batch-to-batch reproducibility and quality.

Guard cartridges are suitable for reversed-phase chromatography because they are all chemically modified in terms of carrying hydrophobic n-octadecyl groups on the surface of the monolithic silica rod. Guard cartridges consist of three pieces. Guard cartridge kits consist of three pieces of guard cartridges, a cartridge holder, and a wrench. The column coupler features two 10-32 male connectors for female inlets of column.
