QUANTITATION AND ANALYSIS OF DROPLETS EJECTED FROM AN INKJET DEVICE

摘要

A method for determining either the mass of one or more drops dispensed from an inkjet dispensing device or the concentration of dissolved solutes form one or more drops of a liquid of interest dispensed from an inkjet dispensing device utilizes UV visible spectroscopy. The UV absorption spectra o the constituents of the solution may be compared to predetermined calibration curves to accurately determine mass and concentrations of a single drop.
