The screw cap may be subjected to baking; however, this does not apply to the septa. It is recommended to obtain new caps, as there is no guarantee for effectively cleaning the used ones, and no established procedure for this purpose is available.

General description
This magnetic screw cap has been developed for the CTC instrument. The vial has a precision thread with numberous threads to force the septa against the vial to seal it to be gas tight. The center hole is designed to be used for SPME as well as standard Headspace analysis, but still offers enough surface for the magnet to transport a completely filled vial.

Protocols
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination in terms of sensitivity and selectivity.
Se probaron el alto rendimiento, la fiabilidad y la reproducibilidad de la microextracción en fase sólida en espacio de cabeza (HS-SPME) en combinación con cromatografía de gases/espectrometría de masas (GC/MS) para la determinación de los compuestos orgánicos volátiles (COV) en agua en un ensayo interlaboratorio. La nueva ISO 17943 en la que se utiliza HS-SPME supone una mejora de los métodos oficiales existentes para esta determinación en cuanto a sensibilidad y selectividad.

Is it acceptable to heat the Magnetic Screw Cap for Headspace Vials, 18 mm thread, at 350°F / 177°C? Is there a recommended procedure for heating these caps to clean any residual substances or to prevent ghost peaks in SPME analysis?
