A simple, rapid, sensitive and accurate spectrophotometric method has been established for determination of rifampicin in pure form and pharmaceutical preparations by using merging zone-continuous flow injection analysis technique. The proposed method based on formation of a violet blackish colored complex between rifampicin and copper ion (II) at absorptivity maximum (565nm). Chemical and physical parameters of this system were investigated. Beers law was obeyed in the concentration range of (5-100μg.mL-1) with detection limit (3μg.mL-1) and Dispersion coefficient (1.28). The analytical parameters were optimized as the fallowing: flow rate is (2ml.min), reaction coil is (75cm), volume of rifampicin is (150μL), volume of copper ion is (125 μL), and concentration of copper ion is (100μg.mL-1). The method was successfully applied to the analysis of the rifampicin in its pharmaceutical preparations.

Abstract A kinetic study of the reactions of 5-hydroxymethyl-2-furfuraldehyde and furfural with 2-thiobarbituric acid (TBA) by a stopped-flow flow injection analysis technique has been undertaken. A semiautomatic method for the analytical determination of these furanic aldehydes is proposed on the basis of reaction with TBA. The proposed stopped-flow method was successfully applied to several commercial pharmaceutical preparations and food samples. The procedure is faster than the earlier procedure for determination of these compounds in foods and pharmaceuticals.

Abstract We describe a procedure for measuring total CO2 in plasma, based on the principles of the flow-injection analysis technique, which makes use of unsegmented fast-flowing reagent streams, as developed by Růziĉka and co-workers. The further methodological design resembles the silicone-rubber membrane technique of Kenny and Cheng. CO2 in the sample is released by reaction with H2SO4. Appropriate amounts of CO2 permeate through the membrane that separates the acid reagent streams and a buffered cresol-red indicator system. The experimental set-up and functioning of this system are described.
