reverse-phase chromatography

The nitration reaction products of phenol in AOT/ isooctane/ water, CTAB/ n-Decyl alcohol/ isooctane/ water and DBSA/ isooctane/ water reverse microemulsion systems were investigated by gas chromatography inner mark method;

采用气相色谱内标法研究了苯酚在AOT/异辛烷/水、CTAB/正癸醇/异辛烷/水、DBSA/异辛烷/水3种反相微乳液中进行硝化反应的选择性；

Methods The quick and sensitive HPLC-UV method was established with carbamazepine acting as internal standard. After the rats were douched with dodder seed, drug-containing serum samples of rats were separated and measured on C18 reverse-phase chromatography column after being liquid to liquid extracted.

方法采用高效液相色谱-紫外检测法（HPLC-UV），以卡马西平为内标，菟丝子灌胃给药后，大鼠含药血清样品经液-液萃取后在C18反相色谱柱上进行分离测定。
