General description

Los montajes de fibra SPME pueden reutilizarse hasta para 100 análisis, o más, dependiendo de la aplicación y del cuidado que se tenga. Para reutilizarlos, basta con acondicionar con calor antes y después de cada análisis. Puede utilizarse disolvente para aplicaciones HPLC o cuando el calor no limpie suficientemente la fibra. Cada montaje tiene un código de color o eje con muescas que indican el tipo de recubrimiento de la fibra. Las moléculas más pequeñas son retenidas en los poros de las fibras que contienen adsorbentes en el revestimiento, como las partículas de carboxeno y de divinilbenceno.

Features and Benefits

Diseñado para utilizar con sistema de sellado Merlin Microseal; puede ser utilizado con otros sistemas sin septum.

Other Notes

El aspecto puede variar. Pueden verse puntos más oscuros en la fibra, pero no afectarán al rendimiento.

Footnote

El recubrimiento está unido a un núcleo flexible de sílice fundida, produciendo un recubrimiento más estable en una fibra menos frágil. Puede haber una diferencia ligera en la selectividad de la extracción comparada con el mimo recubrimiento sobre un núcleo estándar de sílice fundido. El dispositivo de fibra de 2cm no tiene muelle.
