CA 2574616

A method and apparatus for producing an effect of a chemical or biochemical agent on a system responsive to such agent, are disclosed. In practicing the method of the invention, the system is placed within the region of magnetic field of an electromagnetic transducer to which is applied, a low~frequency, time-domain signal characterized, on spectral analysis, by a plurality of agent-specific spectral peaks. These spectral peaks are identified from tht spectral plot of a low-frequency, time-domain signal produced by: (i) placing such a chemical or biochemical agent in a container having both magnetic and electromagnetic shielding, and (ii) recording a low-frequency, time-dependent signal from the sample while injecting noise into the sample at a noise level effective to produce such identifiable spectral peaks in a spectral plot of the time~domain signal. The sample is exposed to the magnetic field produced by the transducer, at an applied signal power and for a period sufficient to produce in the system an agent-specific effect on the system.

L'invention porte sur un procédé et un appareil faisant produire un effet par un agent chimique ou biochimique dans un système réagissant à un tel agent. Pour mettre en pratique ledit procédé, on place le système le champ magnétique d'un transducteur électromagnétique et on lui applique pendant une plage de temps un signal basse fréquence donnant par analyse spectrale plusieurs pics spécifiques de l'agent. L'identification desdits pics dans la réponse spectrale audit signal se fait: (i) en plaçant un tel agent chimique ou biochimique dans une enceinte à blindage magnétique et électromagnétique, et (ii) en enregistrant le signal à basse fréquence produit dans le temps par l'échantillon tout en injectant dans l'échantillon du bruit à un niveau suffisant pour produire lesdits pics spectraux. L'échantillon est exposé au champ magnétique produit par le transducteur et on alimente le système pendant une période suffisante pour y produire un effet spécifique de l'agent.
