The optimal elutingsolvent was the water solutions of 30% ethanol(6 times of resin volume) and 50% ethanol(6 times of resin volume).
而30%乙醇（6倍柱床体积）和50%乙醇（6倍柱床体积）组合是最佳动态洗脱剂。

Compared with the method of single-elutingsolvent, this method increased the selectivity of fixed phase to phospholipid, moreover there are no toxic residue in the final products.
该方法与单一溶剂洗脱相比，增加了固定相对磷脂的选择性，而且在终产物中无毒性物质残留。

System suitability tests may evaluate peak shape; separation of themain peak from solvent disturbance and from closely eluting peaks; andinjection precision.
