Abstract

1. Устройство образования бескапельного ионного потока при электрораспылении анализируемых растворов в источниках ионов с атмосферным давлением, включающее капилляр, в торце которого расположен мениск распыляемого раствора и коаксиально которому расположен внешний капилляр большего диаметра, коаксиальный зазор, подключенный к воздушному откачивающему насосу, плоский противоэлектрод, отличающееся тем, что капилляр с мениском распыляемого раствора находится под нулевым потенциалом, противоэлектрод с отверстием в центре закрыт скользящей заслонкой, которые электрически соединены между собой и подключены к высоковольтному регулируемому источнику питания.2. Устройство по п. 1, отличающееся тем, что мениск ориентирован под углом к горизонтальной плоскости оси отверстия противоэлектрода.1. A device for the formation of a droplet-free ion flow during electrospray of the analyzed solutions in ion sources with atmospheric pressure, including a capillary, at the end of which there is a meniscus of the sprayed solution and coaxially to which there is an outer capillary of a larger diameter, a coaxial gap connected to the air pump, a flat counter electrode, characterized the fact that the capillary with the meniscus of the sprayed solution is at zero potential, the counter electrode with the hole in the center is closed a damper, which are electrically interconnected and connected to a high-voltage regulated power supply. 2. The device according to claim 1, characterized in that the meniscus is oriented at an angle to the horizontal plane of the axis of the counter electrode hole.
