%X A new method for predicting the retention time of solutes under linear gradient elution has been established In this method, the migration distance of solutes in column and the mobile phase gradient were modified simultaneously according to the distribution of mobile phase in column The prediction results of retention time of both weakly and strongly retentive solutes were accurate in different instrumental systems using this method In order to test and verify this method, the retention time of fifteen amino acids and eight homologous compounds of benzene were predicted The predicted results were compared with those predicted by the method in common use The relative average errors between predicted and experimental values were 3 70% and 4 90% for the weakly retentive solutes, far smaller than those obtained by the reference method (23 61% and 31 16%) For the strongly retentive solutes, the relative average errors were 0 21% and 6 01% respectively, slightly smaller than those obtained by the reference method (0 81% and 6 69%) It is seen that this new method has many advantages
