Abstract

Un método para la detección y/o análisis de compuestos que presenta, simultáneamente, resonancia cuadrupolar nuclear y resonancia magnética nuclear, teniendo dichos compuestos un grupo de núcleos de espines A capaces de resonar cuadrupolarmente; y un grupo de núcleos de espines B, capaces de resonar magnéticamente, en donde dicho método comprende: a) aplicar un primer campo magnético H1 sobre dicho grupo de núcleos de espines A, oscilando dicho campo H1 en la frecuencia de resonancia cuadrupolar de dicho grupo de núcleos de espines A, y simultáneamente sobre dicho grupo de núcleos de espines B, otros dos campos magnéticos segundo y tercero, siendo dicho segundo campo magnético un campo magnético H0 el cual se enciende en coincidencia con el primer pulso de dicho campo magnético oscilante H1; y siendo dicho tercer campo magnético, un campo magnético H2 que oscila en la frecuencia de resonancia magnética de dicho grupo de núcleos de espines B en dicho campo magnético H0; b) apagar dicho segundo campo magnético H0 cuando la senal de resonancia cuadrupolar proveniente de dicho grupo de núcleos de espines A es máxima, para que la relación senal-ruido de dicha senal cuadrupolar aumente, y en consecuencia disminuya el volumen mínimo del compuesto posible de detectar y/o analizar; c) digitalizar y sumar las senales detectadas mientras H0 está apagado, en sincronismo con la secuencia de pulsos de excitación para H1; d) encender nuevamente el campo magnético H0, una vez finalizada la etapa de digitalización; e) repetir las etapas b) a d) hasta obtener la relación senal-ruido adecuada para detectar dicho compuesto; y f) emitir una senal de alarma en el caso de detección y/o análisis del siguiente compuesto en el caso de senal negativa. Más específicamente, el método está relacionado con la detección y/o análisis de compuestos, particularmente explosivos, alcaloides, o lo similar, localizados en diferentes tipos de contenedores, en particular equipajes, envíos postales, o lo similar. También se divulga un método para la detección y/o análisis de compuestos que presenten, simultáneamente, doble resonancia cuadrupolar, elementos sensores, y una disposición para la detección y/o análisis de compuestos que presenten, simultáneamente, doble resonancia cuadrupolar nuclear o resonancia cuadrupolar nuclear y resonancia magnética nuclear.
