Organic Acid Analyser
Organic Acid Analyser based on an Ion Chromatography (IC) system is a sophisticated analytical tool used to detect and quantify organic acids. IC has been employed for ion analyses in solution samples obtained from various fields, such as semiconductor cleaning solutions, bodily fluids, and food, as well as for water quality control of river water or drinking water. The analyte ions in IC are mainly the common ions (e.g., Cl–, NO3–) found in environmental water or drinking water samples, but have also extended to weak acids, such as carboxylic acids, silicate and fluoride ions, owing to the wider range of targeted samples. However, the low resolution among weak acidic anions has been an important drawback of conventional IC and the instrumentation for it has undergone significant changes.
