基于气相色谱馏出曲线公式导出了其导数馏出曲线方程 ,进而提出导数色谱法原理。导数色谱曲线峰高、峰面积与试样质量浓度呈良好的线性关系 ,其灵敏度和敏感度得到明显改善。 Based on the gas chromatographic distillation curve formula derivative derivative curve equation, and then put forward the principle of derivative chromatography. The peak height and peak area of ​​the derivative chromatogram showed a good linear relationship with the sample mass concentration, and the sensitivity and sensitivity were significantly improved.
