Tap Water Analysis for Anions and Cations Using Metrohm Intelligent Partial Loop Technique (MiPT)

Partial loop injection is a well known way of sample introduction to HPLC. In ion chromatography, it is not yet used to a large extent. Liquid handling with Metrohm’s Dosino technology now enables the use of partial loop injection on a highly reproducible and accurate level. This application note demonstrates its use for parallel anion and cation determination in tap water analysis.
