  • TRANSDERMAL SAMPLING STRIP AND METHOD FOR ANALYZING TRANSDERMALLY EMITTED GASES
    Publication number: 20210068719
    Abstract: Transdermally emitted gasses are detected by applying a dermal sampling strip to the skin of a biological subject, capturing the gasses in a vapor space in the dermal sampling strip, and analyzing for at least one such gas captured in the vapor space of the dermal sampling strip. Analysis is preferably performed using an electrocatalytic cell, which can be mounted on the dermal sampling strip and form a wall of the vapor space.
    Type: Application
