A container is disposed in such a way that a liquid-state refrigerant mixture of the nonazeotrope refrigerant mixture in a saturated state is temporarily stored with set quality. By measuring temperature and pressure of the liquid-state refrigerant mixture, concentration of the liquid-state refrigerant can be calculated from a database regarding a relationship between a saturation vapor pressure, temperature, quality, and concentration of the previously-stored nonazeotrope refrigerant mixture in the saturated state. Thus, a configuration for measuring the concentration of the liquid-state refrigerant-absorbent mixture includes a container, a temperature sensor and a pressure sensor and thus is very simple and the cost for the configuration can be reduced. In addition, the container can be easily mounted on existing equipment without disturbance of a flow.

Abstract: Metallocorrole complexes of third row transition metals (see Formula I below) may be used as therapeutic agents, catalysts, components of oxygen detectors, and components of light emitting diodes. In particular, metallocorrole complexes of third row transition metals may be used as improved photosenitizers in photodynamic therapy; as improved catalysts in aziridination, epoxidation, and water splitting reactions; as improved in vivo imaging agents; and as improved components in the emissive layer of OLEDs. Due to their strongly sigma-donating nature, corroles are able to stabilize third row transition metals in high oxidation states. Third row transition metals are significantly more electropositive than their first and second row counterparts and may therefore act as improved catalysts.
