Flow-Injection Methods in Water Analysis—Recent Developments

“…To some extent, these articles indicate the selection of the determined analytes, describe the detection methods employed, and show the configurations of the flow-injection systems developed. Among the analytes that have been determined, one can find trace amounts of numerous organic compounds [57,58], the residues of pharmaceuticals [59], and also many groups of inorganic analytes [60][61][62], including nutrients in oceanographic measurements [63], as well as the environmentally significant radionuclides [64][65][66]. Flowinjection analysis methods are also employed in the determination of the total indices of water quality [57][58][59][60][61][62][63][64][65][66][67].…”

Due to their usually rapid determinations, they are effective in the on-line monitoring of drinking water quality and can be employed as early warning analytical systems [68].…”

Immobilized Sorption-Colorimetric Microprobes for Chemical Analysis

“…The use of such columns made it possible to reduce the volume of analyzed samples and to automate the analysis by injecting the entire volume of eluate directly into the instrument. Thus, flow atomic absorption methods for the determination of metals [1] or sorption-chromatographic methods for the determination of organic compounds [2,3] are known. These methods involve the quantitative extraction of analytes when the process is carried out in a dynamic mode [4].…”
