Apparently you mean the work of adhesion. It characterizes the strength of the adhesive bond and is determined by the work of the reversible rupture of the adhesive bond, referred to the unit area (J / m2). The Dupre-Young equation allows us to calculate the work of adhesion if the surface tension of the fluid and the contact angle are known.
A good information source could be the apparatus manufacturer website. See for example https://www.kruss-scientific.com/services/education-theory/literature/application-reports/ in which you will find at least bibliography.
