摘要：

A mixture of substituted triazine and triazole herbicdes is separated on an analytical-scale column by gradient elution using supercritical fluid CO2 with increasing methanol content and flow-rate. High efficiency and fast analysis times are achieved with complete resolution of all the compounds. The effect of CO2 flow-rate on the separation has been studied and it is shown that an increase in the overall mobile phase flow-rate by a factor of two reduces the analysis time drastically with no loss in resolution. Also, the effects of the oven temperature and the column outlet pressure on the separation have been studied. © 1990.
