Abstract
A method for measuring a surface tension of a liquid is carried out using an electrospraying apparatus connected in a system. A voltage source applies a voltage between a capillary through which the liquid is drawn and an electrode of the electrospraying apparatus. An ammeter continuously measures current flowing in the system and if no current or a current less than a predetermined threshold current is measured in the system, the strength of the electric field at the capillary is increased. As soon as current is measured in the system, a reading of a parameter of the system is taken, which is used to calculate the surface tension of the liquid.
