摘要： 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.

摘要： Embodiments disclosed herein provide apparatuses and methods for verifying dispense of a fluid from a dispense nozzle. According to one method, a path of electromagnetic radiation from a source to a receiver is obstructed with the fluid dispensed from the dispense nozzle. The intensity of the electromagnetic radiation received by the receiver is measured. The measured intensity is compared with a predetermined intensity to verify the dispense of fluid from the dispense nozzle. One apparatus for verifying dispense of a fluid comprises a source of electromagnetic radiation, and a receiver of the electromagnetic radiation from the source of the electromagnetic radiation operatively associated with the source of the electromagnetic radiation such that the electromagnetic radiation from the source is received by the receiver. A path followed by the electromagnetic radiation from the source to the receiver is offset from the fluid exiting end of the dispense nozzle by a predetermined distance such that dispense of fluid and a major drop of fluid depending from the fluid exiting end of the dispense nozzle obstruct the path and such that a minor drop of fluid does not obstruct the path.
