A photoacoustic gas sensor includes a photoacoustic cell configured to receive a gas mixture having a first gas component and a second gas component. The photoacoustic gas sensor also includes a light source configured to provide light to the photoacoustic cell. The photoacoustic gas sensor further includes a photoacoustic cell controller configured to measure a concentration of the second gas component using a speed of sound through the gas mixture, where the speed of sound is determined based on an absorption associated with the first gas component. In addition, the photoacoustic gas sensor could include a temperature sensor configured to measure a temperature of the gas mixture, where the photoacoustic cell controller is configured to determine the concentration of the second gas component using the speed of sound and the temperature.
摘要:
A system for testing and calibrating gas sensors with gas stored in a strip of packets. The strip may be fed into a chamber having a defined volume of air. A packet may be punctured with a mechanism to release one or more gases into the volume of air to result in an air-gas mixture. New air may be moved into the chamber to push the mixture out of the chamber to a sensor for testing and/or calibration. Then another packet may be punctured to release one or more gases into the volume of new air in the chamber for another air-gas mixture. This mixture may be moved out of the chamber, in the same manner as the previous mixture, to another sensor for testing and/or calibration. This procedure may be repeated with additional packets on the strip.
摘要:
Embodiments of the present invention relate a gas sensor comprising a gas detector and a hydrocarbon gas generating device, wherein the hydrocarbon gas generating device is positioned to provide an amount of hydrocarbon gas to the gas detector for testing. The hydrocarbon gas generating device comprises a heater and a gas releasing material.
摘要:
Embodiments of the present invention relate to a gas sensor system comprising a gas sensor, a fluid reservoir enclosing a fluid and in proximity to the gas sensor and a membrane positioned between the gas sensor and fluid reservoir, wherein the membrane allows a sufficient amount of a test gas generated from the fluid to contact the gas sensor for testing. Embodiments also relate to a method of testing a gas sensor, the method comprises contacting reagents within a fluid reservoir, generating a test gas and contacting a gas sensor with the test gas sufficient to test the gas sensor.
摘要:
The present invention concerns a method of treating CD14-mediated host inflammatory response to LPS often associated with sepsis comprising administering a therapeutically effective amount of anti-CD14 antibody molecules. A therapeutic composition comprising anti-CD14 antibody molecules in a pharmaceutically acceptable excipient is also contemplated.
