摘要： A sensor that determines information related to a gaseous analyte in a body of fluid. The sensor comprises an emitter, a luminescable medium, a radiation sensor, and a processor. The emitter emits electromagnetic radiation having an oscillating intensity. The luminescable medium communicates with the body of fluid and emits luminescent radiation in response to the received electromagnetic radiation. The radiation sensor receives the luminescent radiation, and generates an output signal based on the intensity of the received luminescent radiation. The processor samples the output signal generated by the radiation sensor at two or more predetermined periodic points over the oscillation of the intensity of the electromagnetic radiation to determine information from the samples related to a phase difference between the oscillation of the intensity of the electromagnetic radiation emitted by the emitter and oscillation of the intensity of the luminescent radiation received by the radiation sensor.

摘要： A gas measurement system of this invention includes a detector assembly having a beamsplitter adapted to separate infrared radiation into a first beam and a second beam and a mirror adapted to receive the first beam from the beamsplitter. The first and second beams are directed to first and second detectors that are disposed in a common plane. In one embodiment, the optical elements are provided on or in an optical block. In another embodiment, the gas measurement system includes a housing that contains an infrared absorption gas measurement assembly, a luminescence quenching gas measurement assembly, and a processor that is programmed to measure gas constituents of a gas flow based on an output of the infrared absorption gas measurement assembly and the luminescence quenching gas measurement assembly.
