Abstract
A system and method for monitoring user exposure to toxic compounds are described. Compounds monitored are preferable volatile organic compounds including benzene, toluene, or xylene. An adsorbent badge is provided for wearing by a user; this is subsequently analysed by means of a field asymmetric ion mobility spectrometer. Multiple badges may be provided to different users, each associated with a unique user identifier.
Claims25
A method of monitoring exposure of a user to a substance, the method comprising:
- providing the user with a wearable adsorbent article suitable for adsorbing and retaining the substance;
- removing the article from the user, and coupling said article to an ion mobility spectrometer;
- desorbing adsorbed substance from the wearable article, such that the substance enters the spectrometer;
- and
- determining the amount of substance present in the spectrometer.
A method of monitoring exposure of a volume to a substance, the method comprising:
- providing the volume with an adsorbent article suitable for adsorbing and retaining the substance;
- removing the article from the volume, and coupling said article to an ion mobility spectrometer;
- desorbing adsorbed substance from the article, such that the substance enters the spectrometer;
- and
- determining the amount of substance present in the spectrometer.
A kit for monitoring exposure of a user to a substance, the kit comprising:
- one or more wearable adsorbent articles suitable for adsorbing and retaining the substance;
- and
- an ion mobility spectrometer.
A kit for monitoring exposure of a user to a substance, the kit comprising one or more wearable adsorbent articles suitable for adsorbing and retaining the substance;
- and instructions for use of the adsorbent article with an ion mobility spectrometer.
