Metrohm has launched the Metrosep C 4, a cation column with good separation characteristics.
The Metrosep C 4 is the result of advances in synthesis procedures and production processes and has even better separation characteristics than its predecessors, the Metrosep C 2 and Metrosep Cation 1-2 column types.
The Metrosep C 4 column has a clearly improved peak shape which leads to a better separation of the individual peaks.
Direct comparison has revealed that using the Metrosep C 4 the number of theoretical plates per metre is higher than that obtained on the Metrosep C 2 or Cation 1-2 columns.
Additionally, for standard cations, transition metals and amines, the Metrosep C 4 column shows better results with regard to peak shape, peak height, resolution, and asymmetry factor.
Especially for monovalent cations, the C 4 column achieves a high number of theoretical plates per metre, thus yielding good detection limits and an improved separation of sodium and ammonium.
