  • DUST AND SPLASH-PROOF FILTER
    Publication number: 20220143559
    Abstract: Embodiments relate generally to a filter, for example, for attachment onto a gas detector device or a gas sensor, and attempt to improve the efficiency and service life of the filter. Embodiments typically comprise a dustproof membrane and a waterproof membrane. Some embodiments may also comprise a splash-proof cap and/or features to reduce negative pressure on the filters.

  • Collection surface for electrodes in photoionization detector
    Patent number: 10996197
    Abstract: Embodiments relate generally to systems and methods for shielding electrodes (204,205,504,505) within a photoionization detector (100). A photoionization detector (100) may comprise an ultraviolet radiation source (130); one or more detector electrodes (204,205,504,505); one or more collection surfaces (224,225,524,525) extending vertically from the detector electrodes (204,205,504,505); and a shielding material (206,506) located between the ultraviolet radiation source (130) and the one or more detector electrodes (204,205,504,505), wherein the ultraviolet radiation (130) does not directly impinge on at least a portion of the one or more detector electrodes (204,205,504,505). The one or more collection surfaces (224,225,524,525) may comprise a surface area that is not covered by the shielding material (206,506).

  • Shielding for electrodes in photoionization detector
    Patent number: 10942061
    Abstract: A photoionization detector (100) comprises an ultraviolet radiation source (130); one or more detector electrodes (204 and 205); and a shielding material (206) located between the ultraviolet radiation source (130) and the one or more detector electrodes (204 and 205), wherein the ultraviolet radiation (240) does not directly impinge on any part of the one or more detector electrodes (204 and 205). A method for gas detection comprises exposing a photoionization detector (100) to an environment containing a target gas; and shielding the one or more detector electrodes (204 and 205) from direct impingement from the ultraviolet radiation (240) via the shielding material (206).
