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.

Metodo innovativo per la determinazione di composti organici volatili in acqua mediante SPME e GC/MS ISO Standard 17943

Un trial interlaboratorio ha validato l’alto livello di efficacia, affidabilità e riproducibilità di un metodo di determinazione di COV mediante HS-SPME seguita da GC/MS. Il nuovo metodo ISO 17943 con l’impiego di HS-SPME segna un progresso, in termini di sensibilità e di selettività, rispetto agli attuali metodi ufficiali in uso per questa determinazione.

Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943

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.

Optimierte Bestimmung flüchtiger organischer Verbindungen in Wasser durch SPME und GC/MS: ISO-Norm 17943

Die hohe Leistungsfähigkeit, Zuverlässigkeit und Reproduzierbarkeit der HS-SPME in Kombination mit GC/MS für die Bestimmung von VOC in Wasser wurde in einem Ringversuch nachgewiesen. Die neue ISO 17943 unter Einsatz von HS-SPME stellt eine Verbesserung der bestehenden offiziellen Methoden für diese Bestimmung in Bezug auf Empfindlichkeit und Selektivität dar.
