Abstract

Se describen sistemas y técnicas para la limpieza de un punto de descarga en corona. Un controlador (150) puede estar acoplado operativamente a un punto de descarga en corona (108) para controlar la operación del punto de descarga en corona (108). El controlador (150) y el punto de descarga en corona (108) se pueden incluir, por ejemplo, con un sistema de espectrometría de movilidad de iones (IMS) (100). El controlador (150) puede ser utilizado para operar el punto de descarga de corona (108) a un voltaje de operación por un primer intervalo de tiempo, con o sin un voltaje de pulso más alto adicional, para producir una descarga en corona, y para operar en el punto de descarga en corona (108) a un voltaje de limpieza mayor que voltaje de operación por un segundo intervalo de tiempo posterior al primer intervalo de tiempo para producir una descarga en corona. La eficacia del punto de descarga en corona (108) se puede controlar mediante, por ejemplo, la medición de un voltaje necesario para producir una descarga en corona (108), mediante una corriente producida en el punto de descarga en corona (108) de una descarga en corona, y así sucesivamente.
