Abstract
The integrated calibration method (ICM) is a novel calibration approach merging interpolative and extrapolative modes in a single procedure. Thanks to this strategy, chemical analysis can be performed along with a diagnosis of systematic calibration errors that leads to better accuracy of analytical results. The paper describes how the ICM can be adapted to different flow techniques: continuous flow, flow-injection, and sequential-injection ones. Instrumental systems dedicated to each flow technique have been presented and their operation has been explained. The systems were used for UV/VIS chromium determination in water samples and compared with each other in terms of precision and accuracy of the obtained results along with time and reagent consumption.
