Environmental Context. Miniaturization, portability and automation are three major issues in environmental chemistry research that can be fully accomplished by exploitation of flow-injection based approaches. Actually, the fast response of flow injection makes the analytical data available in real-time, which is especially desirable for environmental monitoring. Although initially devised for liquid-phase assays, flow systems have also proven suitable for automated handling of solid samples, which opens new avenues for the performance of fractionation analysis (e.g., sequential extraction methods) in an automated dynamic fashion.

Abstract. In the present communication, the third generation of flow injection analysis, the so-called micro sequential-injection Laboratory-on-Valve (μSI-LOV), is presented as a miniaturized, automated approach for on-line monitoring of nutrients in different environmental compartments as effected under enclosed and strictly controlled conditions. Special emphasis is placed on coupling μSI-LOV on-line with a recently developed microcolumn to perform dynamic fractionation schemes for ascertaining the availability of phosphorus forms in solid substrates for biota uptake under simulated environmental scenarios.
