An examination has been made of the approach to development of a procedure for indirect measurement of nitrogen and helium concentrations in liquid rocket propellant constituents based on equilibrium distribution between vapor-gas and liquid phases, and detection of temperature, pressure, and thermal conductivity of the equilibrium vapor-gas phase, followed by performance of calculations with due regard for Henry constants.
