METHOD OF ANALYSED SUBSTANCE DELIVERY TO REGISTRATION SYSTEM AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC H01J49/04 G01N27/62 

FIELD: technological processes.

SUBSTANCE: invention is related to development and design of systems for determination of composition and quantity of chemical compounds, in particular, in mass spectrometers and spectrometers of ion mobility, The method of analysed substance delivery in registration system consists in application of analysed substance onto movable element, which is made in the form of revolution solid, with its further displacement in the registration system by means of movable element turn, at that on movable element at least one section with active surface is formed, then movable element is installed with the possibility of adsorption of analysed substance onto active surface, and movable element is turned until active surface with applied analysed substance is introduced into registration system, and after desorption of active substance in ionic and neutral form the active surface is prepared for the next cycle of adsorption with further displacement of movable element. At that reproducible received active surface is used, which is formed by means of creation of structural defects. Device for delivery of analysed substance in registration system consists of movable element, which is made in the form of revolution solid and installed between seals, and facilities for connection of device elements between each other and for installation of seal around the inlet opening of registration system, and also facility for displacement of movable element, at that the movable element contains at least one section with active surface that is installed in the cavity of movable element.

EFFECT: performance of substances analysis in gaseous phase in actual time, without application of matrix and provision of continuous operation of ionic source of registering device.
