Abstract

Se describe una fuente de ionización de superficie que comprende un tubo que tiene un primer extremo, un segundo extremo, y un orificio interior que se extiende a través del tubo del primer extremo al segundo extremo. El primer extremo del tubo se configura para recibir un flujo de gas y el segundo extremo del tubo se configura para dirigir el flujo de gas en una superficie configurada para sostener un analito. Una fuente radioactiva se coloca al menos sustancialmente en el orificio interior del tubo. La fuente radioactiva se configura para formar iones en el flujo de gas mientras el flujo de gas pasa a través del orificio interior. El flujo de gas que contiene los iones se dirige en el analito para al menos ionizar parcialmente el analito.
