The potentials of the third generation of flow injection analysis for nutrient monitoring and fractionation analysis

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. © CISRO 2006.
