Abstract

El aparato OMS tiene un pre-concentrador (9) en su entrada (7). Un pulsador de presión (8) conectado al interior del alojamiento (1) aplica pulsos pequeños alternos de presión negativa y positiva al alojamiento, de manera que se saca e introduce aire de la entrada (7) en una forma de pulsaciones. Esto provoca que el analito sea absorbido por el pre-concentrador (9) pero no permite que el analito entre lo suficiente para ser ionizado y detectado. Después de un tiempo suficiente para acumular una cantidad detectable de analito en el pre-concentrador (9) se calienta para elución. El pre-concentrador (9) se calienta para elución del analito y el pulsador (8) produce un impulso negativo más grande suficiente para extraer al analito liberado lo suficientemente lejos en la región de reacción (3) para ionización y detección.
