Apparatus and method for monitoring characteristics of pharmaceutical compositions during preparation in a fluidized bed

摘要

The present invention relates to a method and apparatus for monitoring characteristics of a pharmaceutical composition during preparation thereof by in the process vessel (1) of a fluidized bed apparatus, wherein a measuring device (11, 11') performs a spectometric measurement on the pharmaceutical composition in a wetting zone (B) into which a processing fluid is injected. The method also comprises the generic use of an optical probe device in spectrometric measurements, the probe device being capable of transmitting a two-dimensional image of radiation emitted from a monitoring area in the process vessel (1).
