GC-MS: herramienta fundamental para el análisis de drogas de uso ilícito

Stashenko, Elena E.; Martínez, Jairo R.

Palavras-chave: Cromatografía de gases, cromatografía de gases acoplada a espectrometría de masas, sustancias controladas, drogas.

Resumo:  La determinación cromatográfica de drogas de uso ilícito presenta retos importantes en varias etapas de la cadena analítica debido a la volatilidad relativamente baja de los analitos, a la diversidad grande de los posibles contaminantes y a las concentraciones bajas en las que se encuentran algunas sustancias de interés. La preparación de la muestra, el uso de agentes de derivación, los modos de operación del espectrómetro de masas para la detección y los diversos campos de aplicación del análisis GC-MS de sustancias controladas se discuten en este artículo junto con la presentación de algunos ejemplos recientes de estas aplicaciones.
