Three alternatives of prism wash systems can be provided:

  1. Steam wash with integral nozzle, see Prism wash with integral steam nozzle
  2. High-pressure water with integral nozzle, see Prism wash with integral high-pressure water nozzle
  3. Steam and water wash for flow cell mounting, see Prism wash with flow through cells

In most of the applications the prism wash is not necessary. However, installing a wash nozzle should always be considered. A prism wash nozzle can be useful in cases where normally no prism coating occurs, for example to clean the prism after a process stop using a manual wash valve. Washing can also be used for operational check (output signal decreases during wash) or as a part of maintenance schedule.
