Calorimetric and calorimetric-fluorimetric methods for the measurement of singlet oxygen concentrations

Considered is the method of isothermal calorimeter intended for the measurement of singlet oxygen (SO) concentrations in oxygen flow. The method is distinguished for its simplicity and does not require expensive equipment. However, by now no calculation methods were available that would grant the necessary properties of the calorimeter at designed conditions. In this our work such calculation method is developed for calorimeters. Compared are the concentrations of SO produced in electric discharge generators as measured by calorimetric and optical methods.
