METHOD AND DEVICE FOR TAKING AIR SAMPLES FOR SUBSEQUENT ANALYZING GASEOUS OR AEROSOL ADMIXTURES Russian patent published in 2007 - IPC G01N1/22 

FIELD: survey and analysis of materials.

SUBSTANCE: method and device can be used when preparing gaseous state samples for checking physical and chemical properties of materials. According to method of surveying changes in chemical and fraction-disperse composition o f toxic matters aerosol cloud, when remote sampling is provided, vapor and aerosol components of toxic agents aerosol cloud are subject to analysis due to aspiration through infected air flow samplers. Multi-command radio control module is used in the method. Module is disposed at some distance from samplers, which module is used for selecting total amount of aerosol cloud, for selecting its fraction-disperse composition and for selecting its vapor component. Samplers are disposed at some distance from each other. Any sampler is provided with radio receiver with its own coded signal. Receiver receives control signal from radio control module and it operates when selecting corresponding sample upon receiving its own coded command signal. In the device for selecting samples of infected air when testing time changes in chemical and fraction-disperse composition of toxic matter aerosol cloud used for subsequent analysis of selected samples, sample selection radio-controlled aids system is made in form of multiple command radio control module disposed at some distance from samplers. Any sampler is disposed at some distance one from another and it is provided with radio receiver having its own coded command signal, which radio receiver operates when selecting corresponding sample upon receiving its own coded command signal. Input of control system is connected with output of radio receiver through relay.

EFFECT: higher efficiency of remote control of samples in wider ranges of matters.
