  • Ammonia detection in dialysis systems
    Patent number: 11173237
    Abstract: A spectroscopic detection system includes a sensor configured to reflect light of a first wavelength associated with a presence of a reference substance on the sensor and configured to reflect light of a second wavelength associated with a presence of a monitored substance on the sensor, wherein the monitored substance flows to the sensor from a circulating fluid. The spectroscopic detection system further includes a detector that has first and second channels for respectively receiving the light of the first and second wavelengths reflected from the sensor and one or more processors in electrical communication with the detector and configured to identify an excess condition of the monitored substance with respect to the circulating fluid based on a ratio of a second amount of the light of the second wavelength received at the detector to a first amount of the light of the first wavelength received at the detector.
    Type: Grant
