Ascentis Express HPLC Columns

by Sigma-Aldrich/Supelco

Ascentis® Express provides the high speed and high efficiency of sub-2 μm particles, but at approximately half the backpressure for the same column length. This lower pressure means that Ascentis Express can be run on conventional HPLC and LC-MS systems, as well as mid-pressure or ultra-high pressure (UHPLC) systems. Lower pressure also means ...

Shimadzu - CTO-20A20AC10ASvp - Liquid Chromatographs

by Shimadzu Scientific Instruments Inc

Large-capacity, forced hot-air circulation units, the CTO-20A/20AC HPLC column ovens precisely regulate the temperature around the column. Automatic fan-speed control varies with the set temperature to provide stable analysis that is not influenced by the ambient temperature.

Luna - C18 Phase - HPLC Columns

by Phenomenex, Inc.

This is the original Luna C18 and can be used when maximum retention of non polars is desired.

Luna - C18(2) - HPLC Columns

by Phenomenex, Inc.

Octadecyl silane ligands are bound to the silica surface, making for a very hydrophobic phase with great methylene selectivity.

Luna - C5 Phase - HPLC Columns

by Phenomenex, Inc.

5-carbon chain ligands are bound to the silica surface offering a lesser degree of hydrophobic selectivity compared to C8 phase columns.

Luna - C8(2) Phase - HPLC Columns

by Phenomenex, Inc.

Octyl silane groups bound to the silica surface with non-polar end capping offer moderate hydrophobic selectivity and virtually eliminate silanol interactions.

Luna - CN Phase - HPLC Columns

by Phenomenex, Inc.

Nitrile groups bound to the silica surface offer a unique polar selectivity under reversed phase or normal phased conditions.

Luna - NH2 Phase - HPLC Columns

by Phenomenex, Inc.

Amino groups bound to the silica surface serve as a weak anion exchanger and offer polar selectivity under reversed phase and normal phase conditions.
