Abstract

An analytical flow system for class demonstrations is proposed. A digital camera monitors the flow-through cuvette, allowing images of the flowing sample to be real-time displayed on a large screen. The demonstration involves in-line formation and monitoring of different coloured cuprate(II) complexes. By taking into account the typical coloration of the gathered images, it is possible to classify the complexes according to their stability constants. Concepts of analytical selectivity and sensitivity are discussed. The flow system is rugged and portable, requiring minute amounts of solutions.
