Protocols

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.
