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.

Improved separation of explosives using a Thermo Scientific Accucore PFP HPLC column

Instrument Type: HPLC

The Thermo Scientific HPLC system is applied for the determination of explosives. The separation is performed on a Thermo Scientific Accucore PFP HPLC column, with UV detection at 254 nm. The separation achieved on the Thermo Scientific Accucore PFP HPLC column is compared to the separation achieved on a Thermo Scientific Accucore C18 HPLC column.
