Abstract

Analysis system for the automatic analysis of body fluids for a plurality of different analytes (parameters). An analytical apparatus incorporates reaction vessels (8) which are transported on the apparatus to various handling stations (10 to 16). The system also includes liquid reagents, which are held in readiness on the apparatus in reagent vessels (9), their volume sufficing for a large number of analyses. In order to achieve a high degree of analytical accuracy with reduced probability of operating errors and without significant increasing of the overall system costs, a calibrator is stored ready for use in liquid form in a calibrator station (17) of the analytical apparatus, the calibration is initiated and carried out fully automatically (i.e. without human intervention) for the various parameters independently of one another. For the initiation of the calibration for a parameter, in at least one system-immanent calibration-influencing variable is determined and combined logically with a control value defined specifically for the respective parameter and the decision on the initiation of the calibration is taken automatically in accordance with the logic combination.
