Solid-phase extractions in flow analysis [PDF]
Anais da Academia Brasileira de Ciências, 2018 Coupling solid-phase extraction (SPE) to flow systems has promoted a synergistic development. Whereas SPE mechanization leads to improved precision and higher sample throughput, as well as diminishes systematic errors and contamination risks, analyte concentration and separation from the sample matrix provides a remarkable impact on detectability and ...
