AN814: US EPA Method 525.2 — Determination of Semivolatile Organics in Water by Solid-Phase Extraction and GC/MS Detection

Instrument Type: Automated Sample Prep

In this Application Note semivolatile organic compounds were determined in drinking water by SPE and capillary column gas chromatography/mass spectrometry.

AN1109: Rapid Determination of Nitrobenzenes in Drinking Water Using Automated SPE with GC-ECD

Instrument Type: GC

Nitrobenzenes are precursors for the production of numerous industrial chemicals and may be released into the environment through wastewater discharge and may contaminate ground and surface waters. This AN demonstrates automated SPE with GC-ECD for the determination of 15 nitrobenzene compounds in drinking water. The automated Thermo Scientific™ Dionex™ AutoTrace 280 SPE instrument was used in conjunction with the Thermo Scientific™ TRACE™ 1310 GC.This work optimizes SPE and GC conditions and the results show high sensitivity for the 15 nitrobenzene compounds specified in HJ 648-2013.

Determination of Chlorophenols in Water according to US EPA Method 528

Instrument Type: GCMS

The application provides a complete analytical workflow for the GC-MS analysis of phenolic compounds in water according to the EPA 528 guideline. The method includes all the steps required to collect, prepare and analyze samples. The extraction and purification of the analytes have been achieved with the Thermo Scientific Dionex AutoTrace 280 SPE for complete unattended operations.
