The chromatography
Did you know?
In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called … 查看更多內容 Chromatography, pronounced /ˌkroʊməˈtɒɡrəfi/, is derived from Greek χρῶμα chroma, which means "color", and γράφειν graphein, which means "to write".
