Abstract
An apparatus for improving the procedure for quantifying the volume of liquid dispensed by a liquid-dispensing mechanism of an analytical instrument. The apparatus of this invention comprises (a) at least one weigh cup; (b) at least one standard mass; (c) at least one transducer assembly to convert a value of weight to an electrical response; and (d) at least one electronic circuit for converting the electrical response to a measurement of volume. This invention provides a method for calibrating readings of the volume of liquid dispensed by a liquid-dispensing mechanism of an analytical instruments so that absolute measurements of the volume of liquid dispensed can be obtained.
