A quartz crystal microbalance/heat conduction calorimeter (QCM/HCC) has been used to determine the nonvolatile residue at the parts-per-million level in 10 µL droplets of methanol and a 45 µL droplet of water. The QCM was used to measure the mass of the nonvolatile residue, and the calorimeter was used to determine the mass of the solvent by the heat required to evaporate the droplet.
