The Avantor® ACE® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.

Supplier: Thermo Fisher Scientific

Based on Core Enhanced Technology, using 4 µm solid core particles, these columns allow users of conventional HPLC methods to enjoy performance far beyond that of columns packed with 5, 4 or even 3 μm fully porous particles. Very high separation efficiencies, using standard HPLC instruments and conditions, provide increased peak resolution and lower limits of detection. An ultra-stable packed bed results in exceptionally robust columns that demonstrate excellent retention and response reproducibility.

Supplier: HELLMA

Suitable for all current spectrophotometers with standard cuvette holder.
