BTEX compounds are key indicators of petroleum-related water contamination and require sensitive, reliable analytical methods to meet environmental and regulatory demands. This application note demonstrates the robust determination of benzene, toluene, ethylbenzene, and xylene (BTEX) in water using the SCION 8300 or 8500 GC equipped with dual FIDs and the EST Evolution and Centurion Purge and Trap autosampler. The method delivers excellent linearity, reliable compound confirmation using dual columns, and effective performance with nitrogen carrier gas—providing a practical and high-performance solution for routine BTEX analysis in water matrices.

Key learnings from this application note :

1. Understand how the SCION Instruments GC paired with the EST Purge and Trap can be used for the analysis of BTEX compounds in water samples.
2. Discover the excellent linearity and repeatability results achieved using BTEX analytical standards.
3. See how analyte confirmation can be accomplished using two different phase GC columns.
