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 of the constituents of the solution may be compared to predetermined calibration curves to accurately determine mass and concentrations of a single drop.
