Analysis of Nitro Compounds
Applications | | SCION InstrumentsInstrumentation
Aromatic nitro compounds play a crucial role in various industrial processes and environmental monitoring due to their toxicity and prevalence as pollutants. Reliable analytical methods are needed to ensure workplace safety, product quality, and environmental compliance.
This application note (AN0056) aims to establish a robust gas chromatography–flame ionization detection (GC-FID) protocol for the separation and identification of common aromatic nitro compounds. Using a SCION GC-FID system, the method targets efficient resolution of eight analytes under controlled temperature and flow conditions.
The sample analysis was performed with the following configuration:
The optimized method successfully separated eight target compounds with clear baseline resolution. Peak identification was confirmed for benzene, toluene, chlorobenzene, ethylbenzene, m-xylene, p-xylene, o-xylene, and styrene. The temperature program provided sharp peaks and consistent retention time reproducibility.
This GC-FID approach offers:
Emerging developments may include coupling GC with mass spectrometry for enhanced specificity, rapid temperature programming for faster throughput, and miniaturized GC systems for field-deployable analysis.
The described GC-FID method delivers reliable, reproducible separation of key aromatic nitro analytes. Its straightforward setup and robust performance make it a valuable tool for laboratories engaged in environmental and industrial monitoring.
