Title (EN) DEVICE FOR DESORPTION IONIZATION
(FR) DISPOSITIF FOR DÉSORPTION-IONISATION
(ZH) 一种解吸电离装置
Abstract:
(EN) A device for desorption ionization, which can generate corona discharge beam in order to ionize a sample at atmospheric pressure. The device includes an air source, an airflow tube(6), an airflow heating tube(11), a metal tube(4), a DC voltage source(8), and a sample support(2). When a gas that is provided by the air source flows into the metal tube(4) supplied with a DC high voltage, there is a visible corona discharge beam can be formed at the tip of the exit of the metal tube(4). After the gas flowed through the airflow heating tube (11), an object which comes from a solid sample is desorbed, and then the object after desorption and particles that occur in corona discharge beam interact with each other for ionization. And then the ions can enter a mass spectrograph or an other ion analyzing apparatus via an ion entrance(3) nearby the ions. Because the corona discharge beam is visible, it is easy to display an area of a target on the object, and the surface profile of the sample also can be scaned.
(FR) Dispositif de désorption-ionisation, capable de générer un faisceau de décharge corona afin d'ioniser un échantillon à pression atmosphérique. Le dispositif comprend une source d'air, un tube (6) d'écoulement d'air, un tube (11) de chauffage de l'écoulement d'air, un tube métallique (4), une source (8) de tension continue et un support (2) d'échantillon. Lorsqu'un gaz introduit par la source d'air entre dans le tube métallique (4) et est soumis à une haute tension continue, un faisceau visible de décharge corona peut se former à l'extrémité de sortie du tube métallique (4). Après que le gaz a traversé le tube (11) de chauffage de l'écoulement d'air, un objet provenant d'un échantillon solide est désorbé, puis l'objet après désorption et des particules engendrées dans le faisceau de décharge corona interagissent ensemble en vue de leur ionisation. Les ions peuvent ensuite entrer dans un spectrographe de masse ou autre appareil d'analyse d'ions via une entrée (3) d'ions proche des ions. Le faisceau de décharge corona étant visible, il est aisé d'afficher une zone cible sur l'objet, le profil de surface de l'échantillon pouvant également être scanné.
