Abstract
Un método para la detección y/o análisis de compuestos que presentan, 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 S, capaces de resonar magnéticamente, estando dicho método caracterizado porque 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 dichos 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 Ho e 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 núcleos de espines B en dicho campo magnético Ho; b) apagar dicho segundo campo magnético Ho cuando la señal de resonancia cuadrupolar proveniente de dicho grupo de núcleos de espines A es máxima, para que la relación señal-ruido de dicha señal cuadrupolar aumente, y en consecuencia disminuya el volumen mínimo del compuesto posible de detectar y/o analizar; c) digitalizar y sumar las señales detectadas mientras Ho está apagado, en sincronismo con la secuencia de pulsos de excitación para h1; d) encender nuevamente dicho campo magnético Ho, una vez finalizada la etapa de digitalización; e) repetir las etapas b) a d) hasta obtener la relación señal-ruido adecuada para detectar dicho compuesto; y f) emitir una señal de alarma en el caso de detección positiva o en el caso de señal negativa proceder con la detección y/o análisis del siguiente compuesto.<EMI FILE="04051043_1" ID="1" IMF=JPEG HE=50 WI=50 >
