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

This application note demonstrates the use of automated SPE with GC-ECD for the determination of 15 nitrobenzene compounds in finished drinking water. The automated Thermo Scientific™ Dionex™ AutoTrace 280 Solid Phase-Extraction instrument was used in conjunction with the Thermo Scientific™ TRACE™ 1310 gas chromatograph using an Instant Connect micro ECD. This work optimizes SPE and gas chromatography conditions and the results show high sensitivity (MDL of 0.02 ug/L) for the 15 nitrobenzene compounds specified in HJ 648-2013.
