Abstract:
A method of detecting an organic residue is provided. The method comprises a step of bringing a liquid A into contact with a surface of a base material; a step of measuring the contact angle (i) of a liquid B on the surface with which the liquid A came into contact; a step of heating and drying the base material; a step of measuring the contact angle (ii) of the liquid B on the dried surface; and a step of comparing the contact angle (i) with the contact angle (ii).
