Abstract
UN METODO DE ESPECTROMETRIA DE MASAS EN EL QUE UNA O MAS SEÑALES DE TENSION AC SUPLEMENTARIAS DE ALTA INTENSIDAD Y UNA O MAS SEÑALES DE TENSION AC SUPLEMENTARIAS DE BAJA INTENSIDAD SE APLICAN A UN CAPTADOR DE IONES (16). LA FRECUENCIA DE CADA TENSION AC SUPLEMENTARIA, SE SELECCIONA PARA HACER JUEGO CON UNA FRECUENCIA DE RESONANCIA DE UN ION QUE TIENE UNA RELACION DE MASA A CARGA DESEADA. LAS SEÑALES DE TENSION SUPLEMENTARIA DE BAJA INTENSIDAD SE APLICAN CON EL PROPOSITO DE DISOCIAR IONES ESPECIFICOS (ES DECIR IONES PRECURSORES) DENTRO DEL CAPTURADOR, Y LAS SEÑALES DE TENSION SUPLEMENTARIAS DE ALTA INTENSIDAD SE APLICAN PARA RESONAR CON PRODUCTOS DEL PROCESO DE DISOCIACION (ES DECIR, IONES DESINTEGRADOS), PARA QUE PUEDAN SER DETECTADOS. EN UNA CLASE DE VERSIONE, LA SEÑALES DE TENSION DE ALTA INTENSIDAD OSCILAN CON LOS IONES DESINTEGRADOS FUERA DEL CAPTURADOR, PARA QUE SEAN DETECTADOS POR UN DETECTOR EXTERNO (24). EN OTRA CLASE DE VERSIONES, CADA SEÑAL DE TENSION DE ALTA INTENSIDAD RESUENA CON LOS IONES DESINTEGRADOS, SOLO EN UN GRADO SUFICIENTE, PARA LA DETECCION POR UN DETECTOR DE CAPTURA (QUE PUEDE TENER UNO O MAS ELECTRODOS (11-13) QUE DEFINEN EL CAMPO DE CAPTURA, O PUEDE ESTAR MONTADO INTEGRAMENTE CON TALES ELECTRODOS).
