Through the chemical reaction, the BSU is charged into siliester derivative that are vaporized into peak, so we can determine the main content of BSU by gas chromatography.
其中BSU是通过化学反应，将其转化生成可以在色谱中气化出峰的硅脂衍生物，再进行色谱法测定。
Derivative gas chromatography is used to analyze the fluorinated compound derived from the gas out of the rare earth concentrates containing fluorine.
应用衍生气相色谱法测定含氟稀土精矿焙烧逸出气体中的氟化物。
