Abstract:
1. A device for measuring the physical and chemical stability of a substance or formulation, comprising: (a) a vibration spectrometer for obtaining spectra of at least one sample of the substance or formulation at defined time intervals and under the same measuring conditions; (b) a storage container for storing the sample under controlled storage conditions between the defined time intervals, wherein the storage container comprises a means for observing the controlled storage conditions; (c) a transport robot for transporting the sample between the vibration spectrometer and the storage container; (d) a computer which controls sequences of sample movements, wherein the computer comprises a control unit with recording means for recording the spectra of the sample; (e) a storage means for automatically storing the spectra of the sample; and (f) an evaluation means for evaluating the stored vibration spectra by means of statistical data analysis thereby determining the physical and chemical stability of the sample.
