METHOD TO DETECT AND IDENTIFY CHEMICAL COMPOUNDS AND DEVICE FOR ITS REALISATION Russian patent published in 2011 - IPC G01N21/73 H01J49/10 

FIELD: instrument making.

SUBSTANCE: device to detect and identify chemical compounds includes chamber of analysed chemical compound entry, chamber of ions analyser, analyser of ions connected to device of data processing. Also device comprises membrane permeable for analysed compounds and arranged between specified chambers, system for supply of sample comprising analysed compound, source of ionisation. Besides, device includes facilities of connection to systems of provision of working atmospheres of chambers, sources of supply and sources of electric working fields. Besides, membrane is arranged with possibility to form ions of analysed chemical compounds on its surface as it is exposed to electromagnet radiation or flow of particles, and source of ionisation is set with the possibility to send electromagnet radiation or flow of particles directly at surface of membrane. At the same time source of ionisation is arranged in the form of source of electromagnet radiation optically joined via scanning device with surface of membrane.

EFFECT: increased sensitivity of method to detect organic compounds, simplified process to produce ions of analysed chemical compounds, reduced requirements to parametres of laser and expanded field of method application and device to detect and identify chemical compounds.
