  • Patent number: 11786898
    Abstract: Systems and methods for conducting designated reactions that include a fluidic network having a sample channel, a reaction chamber, and a reservoir. The sample channel is in flow communication with a sample port. The system also includes a rotary valve that has a flow channel and is configured to rotate between first and second valve positions. The flow channel fluidically couples the reaction chamber and the sample channel when the rotary valve is in the first valve position and fluidically couples the reservoir and the reaction chamber when the rotary valve is in the second valve position. A pump assembly induces a flow of a biological sample toward the reaction chamber when the rotary valve is in the first valve position and induces a flow of a reaction component from the reservoir toward the reaction chamber when the rotary valve is in the second valve position.

  • Publication number: 20230240570
    Abstract: Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

  • Patent number: 11581174
    Abstract: The disclosure relates to a method of operating a secondary-electron multiplier in the ion detector of a mass spectrometer so as to prolong the service life, wherein the secondary-electron multiplier is supplied with an operating voltage in such a way that an amplification of less than 106 secondary electrons per impinging ion results, while the output current of the secondary-electron multiplier is amplified using an electronic preamplifier mounted close to the secondary-electron multiplier with such a low noise level that the current pulses of individual ions impinging on the ion detector are detected above the noise at the input of a digitizing unit. Further disclosed are the use of the methods for imaging mass spectrometric analysis of a thin tissue section or mass spectrometric high-throughput analysis/massive-parallel analysis, and a time-of-flight mass spectrometer whose control unit is programmed to execute such methods.
