以往,我们在色谱教学中也曾强调标准的色谱峰应服从正态分布,现在觉得这一做法欠妥。虽然根据塔板理论作适当近似处理,可以推得标准的色谱峰应当服从正态分布,但同样根据塔板理论,不作任何近似处理,也可证明标准的色谱峰其实是一个前陡后缓的不对称图形(即:拖尾峰)。文献虽曾指出 In the past, we also emphasized in chromatographic teaching that standard chromatographic peaks should obey the normal distribution, which is now considered to be a defect. Although appropriate approximation based on the plate theory can be derived from the standard chromatographic peaks should be subject to normal distribution, but also based on the plate theory, without any approximation, but also prove that the standard chromatographic peak is actually a steep front Asymmetric graphics (ie: trailing peaks). Although the literature has pointed out
