A portable, compact device for measuring blood gases by using the fluorescence decay time as the information carrier is presented. The instrument is based on solid state technology only, thus using LEDs for excitation and a photodiode as detector. A capillary coated on its inner surface with different sensing membranes serves as a sample compartment and an optical sensor element simultaneously. Furthermore, due to inhomogeneous waveguiding in the capillary walls, only the fluorescent light is guided. Technical details of the electronic circuit, the optical design and the instrumental performance will be discussed.
