The data is used for calculating surface free energy (SFE), for example to determine the wettability of a workpiece in preparation for a bonding or coating process. Today’s contact angle instruments deliver reliable, reproducible data in around 1–2 seconds. This automated approach has clear advantages over conventional manual ink-based methods, which are slow, lack reproducibility, and are dependent on the technician’s individual assessment. The latest handheld contact angle instruments, such as the Mobile Surface Analyzer – MSA, for the factory floor or lab open up opportunities for significant improvements in analytical performance in the automotive, aerospace, and other manufacturing industries. These mobile devices, which are light and compact in design, employ two separate droplets of different liquids (water and diiodomethane), delivered via innovative dosing technology. A key advantage of these instruments is that they deliver data used to determine the polar and dispersive components of the SFE. This aspect of the measurement process, which is not feasible with ink-based methods such as dyne pens, provides a very accurate assessment of wettability to maintain or even enhance the quality of our client's products. ### **A changing paradigm in surface quality control** What are the basic challenges and applications of surface activation? Which innovative automated methods (contact angle) are available compared to conventional manual test methods (test inks)? How do mobile measuring devices like the MSA determine the polarity of surface free energy, thus enabling a very accurate assessment of wettability? Find out how this new technique helps you to enhance your quality control.
