气液色谱中的双固定液规律是指同一柱温下,在两种不同的固定相Ⅰ和Ⅱ上同系物的比保留体积的对数之间存在直线关系: InV_g~Ⅰ=BInV_g~Ⅱ+A (1)此规律就是气相色谱常用的“双柱定性法”的依据,最早见于James等人的著作,卢佩章曾接液体均一位能模型进行过理论研究。 The double fixative method in gas-liquid chromatography means that there is a linear relationship between the logarithms of specific retention volumes of homologues in two different stationary phases I and II at the same column temperature: InV_g ~ I = BInV_g ~ II + A (1) This law is commonly used in gas chromatography, “double column qualitative method” basis, first seen in the work of James et al, Lv Peizhang has been liquid one can model a theoretical study.
