Mejora de la determinación de los compuestos orgánicos volátiles en el agua mediante SPME y GC/MS: norma ISO 17943

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.

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.
