Comparison of quartz crystal and gravimetric microbalance. Measurement of the mass deposited on the bottom plate of the ALICE by QCM and gravimetric analysis after nebulization of 1-5 mL of (NH4)2SO4, NaCl, carbon black and ZnO solutions/suspensions with concentrations ranging between 2-10% (salts) and 0.1-2% (carbon black and ZnO nanoparticles). The (dry) mass per surface area as determined by QCM and gravimetry showed excellent linearity (R2 = 0.962) and agreement within 7.3% (slope) over the investigated range from 3 to 160 μg/cm2.
