FIELD: environmental control. SUBSTANCE: conditions under which registration of individual ions takes place are created in cylindrical condenser. Ions of different mass are registered at different distances from condenser inlet. Cylindrical condenser is made up of outer and inner electrodes and blower. Potentially there are two variants of implementation of device: either outer electrode of cylindrical condenser is manufactured in the form of two electrically insulated cylinders or inner electrode comes in the form of two conductive threads electrically insulated one from another. EFFECT: separate measurement of ions having different masses. 6 cl, 2 dwg
