"Determination Of Potassium Iodide Sugary Pills By FIA Spectrophotometry"
Zhongguo Yiyao Gongye Zazhi 1998 Volume 29, Issue 10 Pages 32-34
MA Yong*, TONG De-Yong, SHAO Hong

Abstract: A rapid spectrophotometric method of flow injection analysis (FIA) has been developed for the determination of potassium iodide sugary pills. It is based on the catalytic effect of I- in the reaction of Ce4+-As3+. The I- concentration. range of determination is 0-5.0 µg/mL.

"Determination Of Dissolution Rate Of Zinc Gluconate Tablets By FIA-spectrophotometry"
Zhongguo Yiyao Gongye Zazhi 1996 Volume 27, Issue 8 Pages 365-367
ZHANG Jie-Bin;ZHOU Guo-Hua

Abstract: The experimental conditions for determination of dissolution rate of zinc gluconate were studied by flow injection analysis. The dissolution rate of zinc gluconate tablets from different pharmaceutical factories was determined by the method. The mean recovery was 99.7+-0.78%, RSD=0.32%.

"Flow Injection Analysis Of Content Uniformity Of Fluphenazine Hydrochloride"
Zhongguo Yiyao Gongye Zazhi 1995 Volume 26, Issue 6 Pages 266-268
GAO Jian-Dong; WANG Tao; MA Guang-Ci

Abstract: A spectrophotometry of the content uniformity of fluphenazine hydrochloride (1) in a flow injection analysis system was based on the color-reaction of 1 with palladium chloride, measured at 485 nm. The calibration curve was linear from 0 to 80 µg/ml, the RSD was about 1%.

"Spectrophotometry Of Promethazine Hydrochloride Injection By Flow Injection Analysis"
Zhongguo Yiyao Gongye Zazhi 1994 Volume 25, Issue 7 Pages 318-320
WANG Yu; MA Guang-Ci

Abstract: A spectrophotometric determination of promethazine hydrochloride (I) injection in a flow injection analysis system is based on the reaction of I with PdCl2. The reaction product is measured at 500 nm. The linear range is 0-130 µg/mL, and the coefficient of variation is no more than 1%.

"Determination Of Captopril Tablets And Their Dissolution By Flow Injection Analysis"
Zhongguo Yiyao Gongye Zazhi 1994 Volume 25, Issue 1 Pages 23-25
ZHANG Shao-Hui;LIU Qan;SHUN Ling-Ling;YU YongMing

Abstract: Captopril tablets and their dissolution were determined by FIA with sodium nitroprusside in the buffer solution (pH 12). In the concentration of range of 20-90 µg/mL, the regression equation of the concentration C with the peak height H was C = 1,002 x 10^-5H + 15.49, r = 0.99991). The recovery was 99.7% for 60 µg/ml (RSD = 0.67%, n = 5). This method is rapid and very sensitive.

"Determination Of Cephalosporin C Potency By Autoanalyser"
Zhongguo Yiyao Gongye Zazhi 1987 Volume 18, Issue 4 Pages 163-166
CHEN Li-juan XIE Xue-min

Abstract: Cephalosporin C(I) forms a reaction product with nicotinamide, which further forms a carbonyl addition product with dihydroxyacetone in alkaline medium. The UV absorbance of the final product is proportional to the concentration. of I. The potency of I in fermentation broths is determined by continuous-flow automatic analysis based on the above reactions; 30 samples can be analyzed in 1 h. The range of determination is up to 25,000 int. units mL-1, and results agree with those by HPLC. A flow diagram for the method is given. The method is simple, rapid, specific and sensitive.
