Electrospray ionization device and method

Abstract

The invention relates to an electrospray ionization device and method. The device comprises a voltage interface (1) used for providing an ionization high voltage and a metal foil sheet (2) connected to the voltage interface (1), wherein the metal foil sheet (2) is used for containing an ionization sample (6) and exciting the ionization sample (6) through the ionization high voltage to carry out ionization so as to form electrospray ions (8). According to the method, the electrospray ionization device is used for preprocessing the ionization sample (6) and then carries out ionization. 本发明涉及一种电喷雾电离装置及方法，该装置包括用于提供电离高压的电压接口（1）及连接到所述电压接口（1）的金属箔片（2），所述金属箔片（2）用于装载电离样品（6）并利用所述电离高压激发所述电离样品（6）进行电离形成喷雾离子（8），所述方法采用上述的电喷雾电离装置对电离样品（6）进行预处理后电离。
