Calculation of Advancing and Receding Contact Angles from Experimentally Determined Relationships among Surface Tension, Equilibrium Contact Angle, and Critical Line Force... 

Besides showing the concept of advancing and receding contact angles. Figure 2.23 also demonstrates that gravity plays a critical role in determining... 

Advancing/receding contact angle. Advancing and receding contact angle should be determined with the drop expansion/contraction method. Typically, the measurement starts with a small sessile droplet ( 2 pL), and small amount of test liquid is added at a very slow rate, e.g., 0.2 pL/s. The drop profile is captured as the drop is... 

The use of the titling plate method to determine advancing and receding contact angle is not recommended. The technique is known to have a limited range and measuranent with large hysteresis sample is erratic [31, 32].
