    摘要: The present disclosure relates to methods and apparatus for detecting when respiratory cartridges of a respirator have reached their end-of-service-life. In some instances, two or more respiratory cartridges are removably connectable to a respirator housing, where each of the two or more respiratory cartridges receives ambient air and deliver cleaned air to the respirator housing. One of the respiratory cartridges may be configured to have a lower adsorption capacity than the remaining respirator cartridges. A gas sensor may be situated downstream of the reduced capacity respirator cartridge, and may detect an increased concentration of the targeted gas in the cleaned air delivered by the reduced capacity respiratory cartridge. When detected, an end-of-service-life indication may be provided to the user.

    摘要: 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.
