[Analysis Case] Anion Analysis by Capillary Electrophoresis

By using capillary electrophoresis (CE), it is possible to perform short-time, high-resolution anion analysis.

Capillary electrophoresis (CE) is an analytical method that performs electrophoresis within a capillary column to separate and analyze various components in an aqueous solution. It is characterized by high separation precision and the ability to conduct analyses in a short time. Here, we present a case study of measuring inorganic anions and organic acids using the CE method. **[Analytical Equipment]** SCIEX P/ACE™ MDQ plus **[Analysis Results]** A 16-component mixed standard solution was measured using the CE method. With CE, it was possible to separate and detect 16 components in about 10 minutes, including capillary cleaning and equilibration. In conventional ion chromatography (IC), shortening analysis time and improving analytical precision required switching columns and considering analytical conditions based on the measured components. However, the CE method allows for the separation and detection of multiple components in a short time, making it suitable for high-throughput analysis.
