摘要： To regulate and monitor material concentrations, e.g., sodium chlorite or hydrogen peroxide, measuring cells are employed in which these substances are reacted to completion with another substance, e.g., sulfur dioxide, in an exothermal reaction. The resulting temperature rise is then a measure for the concentration. A simple measuring cell includes a pipe section provided at both ends with mounting devices for mounting in the delivery line conveying the reaction medium. There is mounted in this pipe section a U-shaped pipe section which is open at both ends and has a smaller diameter, and whose two arms extend into the pipe section with a larger diameter. The center section of, and parallel to, is located outside of the larger pipe and is provided with a thermal insulation, a supply line for the reacting substance, and a temperature sensor.

Within this pipe section there is positioned axially a smaller diameter pipe section which is open at both ends, into one open end of which projects the supply line for the reacting substance and at the other end of which a temperature sensor is installed.

摘要： A cumulative thermal loop applied to microcalorimetry of mixing in which a counter current heat exchanger permits the transfer of reaction heat from the mixture product back to the reactants, thus creating a cumulative effect of the reaction heat until at equilibrium the temperature variation is detected which is equal to the original temperature plus a constant times the unitary reaction heat. The system can be duplicated to provide differentiation, and thermal feedback techniques can be applied in order to equalize the temperature of the observation cell and of the reference cell.
