Therefore, the pressure of the gas above a solution is proportional to the concentration of the gas in the solution. Since the FOXY system detects partial pressure of oxygen, the response in a gas environment is similar to a liquid environment in equilibrium with gas. Therefore, it is possible to calibrate the FOXY system in gas and then use the system with liquid samples and vice versa if you utilize Henry's Law. However, Henry's Law does not apply to gases that are extremely soluble in water. The following information illustrates the solubility of oxygen in water at different temperatures.
Temperature also affects the solubility of oxygen in samples.
The net effect of temperature fluctuations is seen as a change in the calibration slope. If this is not practical, then you should calibrate your FOXY system by using the temperature compensation features and measuring temperature and oxygen concurrently. To monitor the temperature of the sensing environment and compensate for temperature fluctuations, temperature electrodes can now be used in conjunction with the FOXY probe. OOISensors Software corrects for changes in data due to temperature fluctuations. Scattering Media Florescence emissions from the ruthenium complex propagate in all directions.
