| Summary: | The invention relates to the generation of desolvated ions by electrospraying to be investigated analytically, e.g. according to the charge-related mass m/z and/or ion mobility. The cloud of highly charged droplets drawn from the spray capillary by a high voltage is usually focused and stabilized by a beam of nebulizing gas surrounding the cloud of tiny droplets. For a fast drying of the droplets, an additional desolvation gas is usually heated to a temperature of up to several hundred degrees centigrade and blown into the cloud of droplets. The invention particularly relates to the heating of the gas which is instrumental in the generation of desolvated ions as part of the electrospraying process without any mechanical or electrical contact between the heating power supply and the heater itself, but rather by heating the heater for the gas using electromagnetic induction.
本发明涉及通过电喷雾产生去溶剂化离子以例如根据电荷相关的质量m/z和/或离子迁移率进行分析研究。通过高电压从喷雾毛细管中吸引出的高度带电的液滴云通常被包围微小液滴云的一束雾化气体聚焦和稳定。为了快速干燥液滴，通常将另外的去溶剂化气体加热到高达几百摄氏度的温度并吹入液滴云中。本 |
