When in-line PAT is applied in industrial processes, the formation of (bio)films or other contaminants on the sensor tip often limits the stability of measurements. Special ultrasonic protocols introduced in the liquid enable sonicwipe to keep sensor surfaces clean and thus increase the period of reliable usage and lower costs from necessary cleaning steps. Furthermore, probe-sensors remain in place, enabling a continuous workflow of the process and minimizing safety risks due to contact with hazardous substances.
A biofilm formed on a Focused Beam Reflectance probe due to fermenting yeast cells.
The film was removed through application of the sonicwipe.
Fouling Index (FI) during the execution of various ultrasound protocols.
Measurement shows the thorough cleaning due to usage of the sonicwipe.
Simultaneous interaction of petrochemical production-waste water on two sensor-dummies (glass surface). The contamination was widely prevented by the influence of the ultrasonic field.
The degree of contamination was assessed through wiping off the dirt with a piece of cloth, based on comparison of the tissue discoloration.
The cleansing effect of the ultrasonic field is clearly noticeable.
