Abstract
Изобретение относится к устройству (аппарату) и способу формирования газообразных ионов из компонентов образца, находящегося в конденсированной фазе, и их анализа. Способ по изобретению характеризуется тем, что одну или более струй жидкости направляют на поверхность исследуемого образца. При этом соударение струи жидкости с поверхностью образца приводит к образованию капель, несущих частицы образца, которые преобразуют в газообразные ионы путем испарения жидкости или, если это требуется, путем ионизации по завершении испарения. Анализ частиц образца осуществляют известным способом.
