OPUS is especially designed for in- and on-line particle size distributions in highly concentrated suspensions and emulsions (up to 70% Vol. typ.) without any need for dilution. Therefore OPUS is best suited for real time monitoring of:

• milling processes

  crystallisation processes

• polymerisation processes

  precipitation processes

  emulsification processes

  volume concentration

  quality control

  research

  etc.

A few examples for successful OPUS applications:

The trend graphic presents the characteristic values (x10, x50, x90 ) of a particle size distribution as a trend drawn over time and shows a typical milling process monitored in real time. Using OPUS this user makes sure the product is milled exactly to the desired quality. No energy and time is wasted. The installation of OPUS can be performed in the re-circulation loop using process adapters from 10-200mm 

This trend graphic presents the characteristic values of particle size distributions analysed during a continuous crystallisation process. The decrease of the x10 value and the rapid increase of the x90 value at the end of the displayed period indicate a problem in the crystallisation process which has been monitored by OPUS. Since OPUS measures the crystal size distribution in real time, this information is available immediately for the control of the process. The known oscillation of continuously operated crystallisers is monitored. OPUS is installed in the re-circulation loop  of the crystalliser and has a length of circa 1400mm in this case. 

Ultrasonic extinction cannot only be applied on suspensions but for the monitoring of emulsification processes as well. Since dilution very often has a significant influence on emulsions,  undiluted OPUS measurements are ideal to monitor emulsification processes. The graphic presents the change of the droplet size distribution by different amounts of energy used for the emulsification.
