气相色谱中的Kováts保留指数是目前最精确的反映溶质与固定相分子相互作用大小的指数系统。现已发表大量的气相色谱保留指数。用气相色谱保留指数预测液相色谱保留值是较好地解决液相色谱保留值预测的途径。在理论上和实际应用中均有较大的意义。
The Kováts retention index in gas chromatography is the most accurate exponential system that reflects the interaction between solute and stationary phase molecules. Has published a large number of GC retention index. Predicting the liquid chromatographic retention value by gas chromatographic retention index is a good way to predict the retention of liquid chromatogram. In theory and in practice are of great significance.
