Process Monitoring of Surface Tension The Process Tensiometer SITA clean line ST continually and automatically measures the surface tension of process liquids used in the parts cleaning industry, surface technology, semiconductor and photovoltaic industry as well as in the chemical industry. The parameter surface tension, and thus the concentration of surface-active agents like surfactants, wetting agents and solvents, are measured and documented inline. Connected to the plant control, the SITA clean line ST measuring system carries out an automatic dosing of active agents according to the...

Application Continual monitoring and dosing according to the consumption: • Cleaning agent component surfactant in baths of industrial parts cleaning • IPA-Concentration in texturing baths for silicon-wafers of photovoltaic industry • Wetting agent concentration of developer solutions for lithography processes of the semiconductor industry The concentration of free surfactants influencing the cleaning power determines the value of the parameter surface tension. Therefore, bubble pressure tensiometers are used in monitoring processes. Air bubbles are produced in the sample liquid with o...
