| Abstract: | This paper reports a simple,rapid and accurate procedure for quantitative
determination of mixtures of polyethylene glyeol oilgomers by RP-HPLC.The meth-
od employs photomertric detection at 195nm using a reversed phaes C_(18)column with
acetonitrile/water(10/90)as the isoeratie cluting system.Linear equation
y=-0.081+0.712x,correlation coffieient r=0.9994,the recovery of 97.4%. |
