chromatography
含义: A laboratory technique for separating a mixture into its individual components by passing it through a medium in which the components move at different rates.
Chromatography is ubiquitous in analytical chemistry, pharmaceutical quality control, forensic science, and environmental monitoring. Gas chromatography and high-performance liquid chromatography (HPLC) are the most commonly cited variants in academic literature. The technique is essential for identifying pollutants, verifying drug purity, and analysing biological samples. In journalism, chromatography appears in reporting on doping scandals, food safety, and criminal investigations.
