Sequential Injection Analysis

Abstract

Flow-based procedures were originally proposed as alternative approaches to batch analysis with the following aims: (a) to enhance the automation of chemical assays; (b) to shorten the analysis time; (c) to improve the accuracy and precision; (d) to reduce the cost (through unattended operation and lower reagent consumption) (Ruzicka, 2014). The temporal evolution of the different versions of ow analysis is illustrated in Figure 2.1.
