A multicommuted flow-through optosensor based on the direct fluorescence measurements of Vitamins B 2 and B 6 using a non-polar sorbent (C 18 silica gel) as solid sensing zone (to accomplish the separation and subsequent preconcentration/detection of the target analytes) have been developed. The proposed flow system was controlled by Java-written home-made software and designed...
In this work, a single solid surface fluorescence based flow-through optosensor has been developed for the determination of trace amounts of cadmium in drinking water samples. The developed methodology is based on the transient immobilization of the target species on an appropriate active solid sensing zone (Sephadex QAE-A25).The target species was the fluorogenic chelate, formed as a result of the...
