Abstract

Procedimiento de identificación de toxinas PSP mediante espectrometría de masas con ionización por nanospray. Procedimiento basado en el análisis directo de volúmenes muy pequeños de muestra, previamente concentrada, mediante ionización por "nanospray" y detección muy selectiva de fragmentos específicos de cada una de las toxinas analizadas mediante espectrometría de masas en tándem (MS/MS). Esta aproximación permite analizar la presencia de las toxinas en mezclas heterogéneas sin problemas de interferencia, y sin recurrir a ningún paso cromatográfico previo para separarlas del resto de los componentes antes de proceder a su detección.
