FIELD: investigating or analyzing of materials.
SUBSTANCE: method comprises sampling, supplying the sample to the cell provided with two piezo-quartz resonators, detecting in static conditions by exposing the resonators to vapors of individual acids and their mixtures, recording analytic signal, plotting calibration curves, and calculating the concentrations from the formulae proposed.
EFFECT: enhanced precision.
