Determination of calcium content in Zofenopril;

Determination of Zofenopril by High Performance Liquid Chromatograpgy

Determination of zofenopril and its active metabolite zofenoprilat by a new derivative LC-MS method and their pharmacokinetics in healthy Chinese volunteers

Aim:A new derivative LC-MS method was developed for the simultaneous determination of zofenopril and its active metabolite zofenoprilat to investigate the pharmacokinetic characteristics of zofenopril and zofenoprilat in healthy Chinese volunteers after single and multiple oral doses of zofenopril calcium tablets.

Study on reducing moisture of superphosphate by pulping waste liquor;

Affecting factors and its variation rules on extrusion granulation of urea-superphosphate granular com pound fertilizer are studied.

The application and economical profit of a new type of mixing reaciton plant for producing calcium superphosphate;

In this paper,a new type of mixing reaction unit composed of injector and baffled chamber,which is used in production of calcium superphosphate

A numerical calculation for the conversion rate of calcium superphosphate products was derived by the a-nalysis of factors on the conversion rate,and a method for the determination of ratio of phosphate ore incomplete decomposi-tion and available phesphate degeneration induced by sesquioxide was put forward,which provided a path for the predictionand adjustment of the process system.
