Abstract
The invention relates to a novel device for determining the physical and chemical stability of substances and formulations by means of samples. Said device is provided with a vibration spectrometer, a container (1) for storing the samples in controlled conditions, a robot (10) for transporting the samples between the vibration spectrometer (12) and the container, and a computer (13) for controlling the processes and for automatically storing and evaluating the spectra of the samples received by the vibration spectrometer.
Claims11
A device for determining the physical and chemical stability of substances and formulations using samples, characterized in that a vibration spectrometer, a container (11) for storing the samples under controlled conditions, a robot (10) for transporting the samples between the vibration spectrometer (12) and the container, and a computer (13) for controlling the sequences and for automatic storage and analysis of the spectra of the samples recorded using the vibration spectrometer are provided.
A method for determining the physical and chemical storage stability of substances and formulations, in which vibration spectra of samples of the substances and formulations are recorded at regular time intervals, characterized in that each individual vibration spectrum of a sample is indexed using the sample number, the storage conditions, and the measurement time, the recorded and indexed vibration spectra are stored in a computer as raw data, and, as soon as the number of stored spectra has exceeded a predetermined threshold value, the raw data of each individual sample is analyzed using statistical data analysis.
