ABSTRACT:
A fiber optic sensor suitable for measuring and monitoring fluid parameters, e.g. blood parameters such as carbon dioxide and oxygen partial pressure and hydrogen ion concentration ( pH ). Analyte sensitive chemistry in such probes includes molecules sensitive to responding to an analyte change in an optically detectable system. Methods of making analyte measuring chemistries including disposing an indicator complex in the path of light and casting over it films of permeable / semi- permeable polymer membranes capable of diffusion of gases and other analytes. A liquid control validation solution ) acts as a simulating standard for blood gas analysis. Liquid calibration solutions which mimic fluids such as blood to validate and test sensors for long term stability.
