Table 2 effect of different elution solvent on recoveries .
不同洗脱剂对回收率的影响。
A substance used as a solvent in the process of elution .
洗提液在洗提过程中作为溶剂的物质。
The effects of initial buffer composition and ph on the gradient elution have been investigated .
考察了梯度洗脱分离时，起始缓冲液组成及ph值对分离的影响。
The dynamic experiments further show that 20 % ethanol and 20 % isopropanol are good for their high elution speed and large distribution ratio of6-apa in the liquid phase etc.
Microprocessor controlled systems are capable of accurately delivering a mobile phase of either constant ( isocratic elution ) or varying composition ( gradient elution ) , according to a defined programme .
