The Metrosep C 4 - 50/4.0 is the shortest separation column in the Metrosep C 4 product range. With a capacity of 5 µmol (K+), it is particularly suitable for very rapid separations. The low capacity makes it possible to quickly analyze the earth alkaline metals with their delayed elution. Thanks to the short retention times, applications that, in terms of analysis duration, were previously possible only with an FIA system (Flow Injection Analysis system) can now be transferred over to ion chromatography.
