Description

The 150 mm version of the Metrosep A Supp 5 is distinguished by its very good separation properties. High plate numbers and excellent peak symmetries facilitate working in the lower µg/L range. The particle size of 5 µm makes a decisive contribution to the separating efficiency of this column. The Metrosep A Supp 5 - 150/4.0 offers the optimum combination of selectivity and capacity, with which even complex separation tasks can be solved within a short time. This property makes the Metrosep A Supp 5 - 150/4.0 one of the best universally applicable standard IC columns.
