Nanologica and Sterling partnership on production of silica particles

ACE CN-ES is a new range of UHPLC and HPLC columns from Advanced Chromatography Technologies Limited.

ACE C18-Amide is a new, uniquely designed UHPLC/HPLC stationary phase offering improved retention of polar compounds, enhanced phenolic resolution and alternative selectivity to C18 bonded columns.

Particulate silica HPLC columns can produce very high pressures and long separation times. In between runs these columns require a lengthy equilibration phase whilst flow rates and column length are limited, writes Dr K Sinz. In summary, particulate columns can seriously limit the number of samples it is possible to analyse.
