Abstract
A method and device for monitoring and controlling a pharmaceutical, chemical or food process, in which the biological activity and/or the bio-mass of micro-organisms in the process is monitored, and in which the state of the process is detected by monitoring viscosity and/or aggregate size and/or content of a dispersion of proteins, crystalline particles or fat droplets that are processed, respectively. The micro-organisms and/or bio-molecules produced in the process, and the proteins, crystals particles or fat droplets being processed are monitored by means of acoustic spectroscopy.
