概要	Inductively coupled plasma spectrometry is a powerful multi-element analytical technique that ionizes a sample in a high-temperature plasma and measures the emitted light (ICP-OES) or ion masses (ICP-MS) to determine elemental concentrations. Developed in the 1960s by Stanley Greenfield, ICP techniques have become the standard for trace element analysis across environmental, geological, biological, and industrial fields. The method combines exceptional sensitivity, wide dynamic range, and the ability to analyze dozens of elements simultaneously.	Ion chromatography is a liquid chromatography method that separates ions and polar molecules based on their relative affinity for the ion exchange resin in the column. Developed by Hamish Small in 1975, it combines ion-exchange separation with conductivity detection, enabling rapid, sensitive, and simultaneous determination of multiple ions in a single analysis. Ion chromatography has become an indispensable tool for monitoring environmental pollutants, analyzing food and pharmaceutical products, and studying complex ionic mixtures.
