Inline process control of wettability by means of contact angle measurement on moving surfaces

The fast Liquid Needle dosing technique and a flexible software interface pave the way for integrated quality testing

Contact angle measurement has completed the step from the test laboratory into the production hall with regard to quality assurance for the cleaning and pretreatment of surfaces. This has been made possible thanks to the development of fast and mobile measuring technologies. We go even further with this feasibility study and show a way for the potential use of contact angle measurements as a test method for uninterrupted inline process controls.  Two of our recent innovations open up this perspective: the extremely fast Liquid Needle technique that enables contact angle measurements on moving samples and the ADVANCE API software interface with which the integration of fully automatic analyses is possible in any complex information systems.
