Flow injection analysis of pharmaceuticals

Journal of Pharmaceutical and Biomedical Analysis, 1989
An overview of the most representative problems solved by flow injection analysis (FIA) in drug analysis is presented. Different aspects of this technique which can be manipulated with specific purposes are discussed and special emphasis is placed on the possibilities of FIA in dissolution test control.

Reduction of injection variance in flow-injection analysis

Talanta, 1992
In order to achieve maximum sensitivity in flow-injection analysis, sample dispersion must be kept to a minimum. This dispersion process, however, is not well understood. Studies of the dispersion process have concentrated on dispersion within the flow manifold while dispersion due to the injection process has been largely ignored.

Flow injection stripping analysis

Electroanalysis, 1991
AbstractA review of the two main electrochemical stripping techniques (voltammetric and potentiometric), associated with flow injection analysis (FIA), is presented. The versatility and flexibility provided by the FIA, manifold for performing unique stripping procedures such as medium exchange, flow reversal, and subtractive operation are evaluated ...

Injection analysis—From flow-injection analysis to batch-injection analysis

Microchemical Journal, 1992
Abstract The performance characteristics of batch-injection analysis (BIA) are evaluated. This nonflow injection technique results in many of the attractive features of flow-injection analysis (FIA) while eliminating the need for a flow manifold. BIA has emerged from the coupling of controlled dispension, wall-jet detection, and huge dilution.

Flow-injection analysis in clinical chemistry

Talanta, 1984
Flow-injection is the most recent addition to the techniques used in automatic analysis. In the simplest form, the sample is injected as a discrete slug into a stream of reagent flowing in a narrow-bore tube. Various sampling valves have been used in order to achieve full mechanization, but are not ideal for clinical analyses since they are wasteful of

Laminar dispersion in flow-injection analysis☆

Talanta, 1981
Simple expressions are given for the dispersion and the travel times of samples in simple flow-injection analysis systems. The sum of these two quantities is the total residence time of the sample in the system. The expressions are based on numerical solutions of the diffusion-convection equation.
