Recent advances in flow injection analysis

Abstract

A dynamic development of methodologies of analytical flow injection measurements during four decades since their invention has reinforced the solid position of flow analysis in the arsenal of techniques and instrumentation of contemporary chemical analysis. With the number of published scientific papers exceeding 20,000, and advanced instrumentation available for environmental, food, and pharmaceutical analysis, flow analysis is well established as an extremely vital field of modern flow chemistry, which is developed simultaneously with methods of chemical synthesis carried out under flow conditions. This review work is based on almost 300 original papers published mostly in the last decade, with special emphasis put on presenting novel achievements from the most recent 2-3 years in order to indicate current development trends of this methodology. Besides the evolution of the design of whole measuring systems, and including especially new applications of various detections methods, several aspects of implications of progress in nanotechnology, and miniaturization of measuring systems for application in different field of modern chemical analysis are also discussed.

Determination of Aniline Blue dye by Flow Injection Analysis With Home Made Valve

“…Reproducibility can be seen in figure 4 it shows the repeating run with response. The unit gave a good reproducibility which agree with results for determination of adsorbed phenol on wheat husk 37 , proscopisfarcta berry 38 , for alkenes determination by merging zone technique 39 and alkenes determination by sequential technique 40 .…”

Online Monitoring of Polymerizations: Current Status

“…[1] A review on recent advances in flow injection analysis was recently given by Kolacinska and coworkers. [2] Operation of such a reactor setup can be used for optimization of polymer reactions that require in-depth product monitoring in order to push limits towards new products that would otherwise be inaccessible or uneconomical to synthesize by any other offline sampling method. [3,4] A different kind of automatization in polymer synthesis is demonstrated by automated parallel synthesizers (Chemspeed reactors).…”

A Miniaturized Flow Injection Analysis System for Electrogenerated Chemiluminescence−Based Assays

“…In addition, sequential injection analysis allows a considerable reduction in the consumption of the sample and reagents. [14] Bearing in mind that ECL based advances are moving towards the development of portable, high-throughput and point-of-care testing systems, [8,15] disposable screen-printed electrodes coupled to a small-sized, non-conventional, FIA system appears as an attractive possibility.…”

In these electrodes a transparent slide, that usefully allows the detection of air bubbles inside the cell, is attached over the screen-printed electrodes platform delimiting a flow channel.…”
