Teaching of process analytical chemistry

In the teaching of analytical chemistry for chemical engineering students it is essential today to teach the chemical analysis of dynamic systems, not only in the process control of the modern technological systems, where the control of composition or structure of different material streams is necessary, but also in all other instances where analysis, decision and intervention follow each other, forming a closed cycle. Teaching can be made effective if students already have a knowledge of the basic disciplines (including analytical chemistry). The schedule of the teaching programme should include the mathematical statistical treatment of process signals, quality of the signals, signal-improvement methods, characteristics of instruments, calibration and an introduction to sensors, analysers suitable for continuous or periodical measurements and local area networks. As practical exercizes an apparatus for investigation of the dynamic properties of a thermoanalytical detector system, a computer program for simulating process variables and the control loop including the measuring system are presented.
