membraPure - Model IONUS -Ion Chromatograph
FrommembraPure GmbH
Designed for the analysis of anions and cations: This IONUS is suitable for the analysis of anions and cations in research, development and everyday routine. The sample solutions are mostly water-based and may contain water-miscible organic solvents. A classic example is the analysis of (drinking) water according to EPA 300 Part A and B. The advantage of IONUS is the compatibility with IC columns of all manufacturers and is compatible with all common eluents of anion and cation chromatography.
