Modern clinical chemistry is characterized by a high degree of mechanization. Today, virtually all steps of the analytical process may be automated. This thesis is a literature research on the forms of automated analysis and their implementation in laboratories. It focuses on possible mechanized analysis methods and the design configuration as well as the function of their components. For this purpose, the principal photometric, electrochemical, electrophoretic, chromatographic, and immunological procedures and their technical realization are examined in detail. A historical excursion provides an insight into the development of laboratory automation over the last 150 years.
