METHOD FOR MEASURING CONCENTRATION OF COMPONENTS IN LIQUID Russian patent published in 2006 - IPC G01N29/02 

FIELD: technology for determining moisture in organic solvents.

SUBSTANCE: sorptionally sensitive element is positioned directly in analyzed liquid. Depending on viscosity of analyzed environment and oscillations frequency of sensitive element, power fed to sensitive element is set by altering power voltage fed to electronic generator in accordance to formula: where P - power, fed to sorptional-frequency sensitive element, Wt; K - proportionality coefficient, numerically equal to 18,5·10³ Wt·Hz/centipoises; η - viscosity of analyzed environment, centipoises; F₀ - nominal oscillations frequency of soprtional-frequency sensitive element, Hz.

EFFECT: increased sensitivity, precision and simplified measuring process.
