Zusammenfassung:The invention refers to a photometer arrangement (8) with a reagent container (10,10′) comprising a reagent (14) and being provided with a machine-readable reagent identifier (16), an analyzer device (30) comprising a photometer (40) for providing a photometric raw measurement value (M), a reagent identifier reader (45) for providing a reagent identity (R) and a photometer controller (36), a time stamp generator (38) for providing a measurement date (MD), a reagent ageing database (76) with reagent-identity-specific and age-specific ageing correction factors (C), and an evaluation device (50) having a data connection with the analyzer device (30) and the reagent ageing database (76). The long time accuracy of the photometric results is improved significantly.
