abstract Volatile amines are sorbed onto the gold electrodes of a quartz piezoelectric crystal, and the observed frequency decrease is used for their quantification. Water increases the observed signal, leading to important errors in the amine quantification. However, the presence of minor amounts of water is readily detected, as the plotted frequency signal shows a marked distortion.
