DEVICE FOR METERING AMOUNT OF TOXIC SUBSTANCES IN ENVIRONMENT Russian patent published in 2000 - IPC

FIELD: environment control engineering. SUBSTANCE: device has sampling facility, sample radioactivity detector, extractor, sample optical density meter, and data processing unit whose inputs are connected to outputs of sampling facility, sample radioactivity detector, and sample optical density meter whose input is connected to extractor output. In addition, device is provided with sample acidity meter; sample radioactivity detector is made in the form of γ-spectrometer for determining total dose of γ and β rays; extractor is designed for extracting amines, amides, nitrites, and nitrates from sample and to obtain sample containing only predecessors of nitroso compounds; inputs of γ-spectrometer and acidity meter are connected to sampling facility and outputs are coupled with data processing unit incorporating data acquisition facility. Device is capable of measuring content of S, O, N, C nitroso compounds in all entities of environment including living organisms. Extremely small amount of sample is required to determine concentration of nitroso compounds. EFFECT: enlarged functional capabilities, improved measurement accuracy. 2 cl, 3 dwg, 1 tbl
