Rivers and lakes provide the raw water supply for our everyday tap water needs. As the raw water quality directly affects human bodies, it must be continuously monitored and analyzed. As the inorganic anion components in river and lake water directly reflect the water source and soil properties, fluctuations in the anion concentrations can be used as indicators of changes in the environment.

Analysis of Lake Water

Ion Chromatograph

This separation/analysis instrument is widely used for the quantitative analysis of inorganic ions. Ion chromatographs are available as the a suppressor type that allows ultra-high-sensitivity analysis to the ppb level and as the a non-suppressor type that supports diverse applications.
