Flow analysis refers to a branch of analytical chemistry devoted to the automation/mechanization of chemical assays by improving precision and sample throughput and minimizing risks of sample contamination and exposure of the analyst to toxic substances. Flow analysis is also recognized as an effective tool to achieve green analytical chemistry (GAC), including reagentless approaches, replacement of toxic reagents, waste minimization, reuse of chemicals and in-line waste detoxification. The main flow modalities of GAC and the approaches to achieve the previously mentioned goals are the focus of this chapter.
