1·Under optimum conditions, lead and cadmium can be enriched and eluted at the same time in the same water sample.
经过最佳条件选择，在同一水样中可以同时进行富集、 洗脱铅和镉。
2·When using green tea as raw material, it is difficult to prepare the qualified decatechin product of GTC-70(EGCG>40) which is eluted with 80% ethanol directly after being adsorbed by A resin.
以绿茶为原料经过A树脂吸附后直接通过80％的乙醇洗脱，难以达到符合低咖啡因的GTC-70（EGCG大于40％）规格的品质要求。
3·They are eluted by both self-elution effect and on-column change of the eluent.
提出了在高浓度基体中，同时存在自身洗脱效应和在线流动相变化两种洗脱机理。
4·The SPE column was washed with water and eluted with acetonitrile.
