The Mobile Surface Analyzer – MSA calculates the wettability of a surface automatically by measuring the water contact angle. The contact angle provides information about the surface characteristics required for further processing, e.g. free surface energy and wettability (important parameters for printing, painting and coating) or adhesion capacity. The machine also reliably indicates the polarity of a surface, for example as a result of activation with Openair-Plasma®.
The MSA uses two test liquids to determine the surface energy of a solid surface – one polar (usually water) and the other non-polar (usually diiodomethane).
At the click of a button, the machine automatically applies the correct dose of the two liquids, measures every contact angle simultaneously and calculates the free surface energy in a process which lasts no more than a second. Since the process is contactless, undesirable contact with the surface and possible contamination or damage to the specimen are avoided.
