Ultrapure Water For Trace Analysis

By Rüdiger Wittlake, Dr. Petra Slabizki, Hans-Thomas Herbst, Carsten Röttger, Dr. Elmar Herbig

The purity of the solvents used, primarily that of water, is a decisive criterion for interference-free and reproducible analysis by liquid chromatography and for the sensitivity of this method, especially for applications in trace analysis. In a study, different sources of ultrapure water used as eluents were compared in high-performance liquid chromatography with diode-array detectors (HPLC-DAD) and mass spectrometry (MS) systems in various experiments.
