Abstract: A method and test apparatus determines a volume of a droplet of liquid. The test apparatus deposits a drop of liquid to be measured on a surface that provides a known contact angle with the liquid under the deposition conditions used, thereby establishing one of: (i) an advancing, (ii) a receding, and (iii) an intermediate contact angle. The test apparatus images the drop. The test apparatus measures a dimension of height or diameter of the drop. In one embodiment, the test apparatus calculates a volume of the drop of liquid from the relationship of the contact angle to one or more parameters selected from the maximum height, the diameter of the contact patch, the radius of curvature, or the cross sectional area of the drop.

Abstract: A method for operating a liquid droplet dispensation system is provided. The method includes dispensing a first droplet of a first fluid sample from a reservoir at a first pressure, measuring a first velocity of the first droplet, and measuring a first mass of the first droplet. The method further includes dispensing a second droplet of the first fluid sample from the reservoir at a second pressure, measuring a second velocity of the second droplet, and measuring a second mass of the second droplet. The method further includes dispensing a droplet of a second fluid sample from the reservoir at a third pressure, measuring a third velocity of the droplet of the second fluid sample, and determining a mass of the droplet of the second fluid sample based upon the first, second and third velocities, the first, second and third pressures, and the first and second masses.
