1958年Kovats首先将保留指数引入气相色谱法中。这一工作大大地推动了气相色谱法的发展。次年,Wehrli和Kovats证明了这个特征值对于气相色谱定性分析有巨大的优越性。(为了与文献值对照进行定性分析,后来ASTM编汇了大量的保留指数数据。)1959年Rohrschneider利用保留指数表示分离柱子的极性和选择性。在1965~1966年Rohrschneider又指出如何予先计算保留指数而仅具有较小的系统误差。1970年Kaiser断言利用高质量的固定相和仪器、严格的数据计算,那么气相色谱定性分析将提供可以在全世界进行比较的实验结果。由于保留指数具有加合性,为此
In 1958 Kovats first introduced the retention index into gas chromatography. This work has greatly promoted the development of gas chromatography. The following year, Wehrli and Kovats demonstrated that this eigenvalue offers great advantages for the qualitative analysis of gas chromatography. (In order to qualitatively contrast with the literature values, ASTM later compiled a large number of retention index data.) In 1959 Rohrschneider used the retention index to indicate the polarity and selectivity of the separation column. In 1965-1966 Rohrschneider also pointed out how to calculate the retention index first with only small systematic errors. In 1970, Kaiser asserted that using high-quality stationary phases and instrumentation with rigorous data calculations, GC qualitative analysis will provide experimental results that can be compared across the world. Because of the additive index, this is why
