Process and measuring system for detection of substances emitted or perspired through the skin |
摘要 |
The process for detection and for quantitative determination of substances emitted or perspired through the skin is derived from flow diffusion analysis. The measuring system conceived for this purpose uses a diffusion half cell through which an acceptor medium flows and which is closed by a membrane. For the duration of the measurement, the membrane is brought into contact with the skin or a closed gas volume formed over the skin. With the process and the related measuring system, the blood alcohol level can be determined with a good degree of precision indirectly via the quantity of (gaseous) ethanol emitted through the skin.
