AN328: Extraction of Explosives from Soils by Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

Compounds used in high explosives may be toxic, carcinogenic, and are found on the Resource Conservation and Recovery Act (RCRA) list. These compounds and their metabolites are monitored in soils and ground waters to ensure compliance with U.S. EPA regulations. This application note reports on the use of ASE for the extraction of explosive compounds such as HMX, RDX, 2,4,6-trinitrotoluene (TNT), and some of their known metabolites from soils.

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.
