This document introduces a single-column technique for analyzing carbon, sulfur, and nitrogen compounds in a gaseous matrix. The analysis is performed with an Agilent 6890 gas chromatograph (GC) and an Agilent G2350A atomic emission detector (AED). An Agilent 30 m × 0.53 mm × 5 µm J&W DB-1 capillary column is used for separation.
This document details an analytical method developed by Agilent Technologies to determine stack and flare gas emissions. The technique utilizes a single-column setup with an Agilent 6890 gas chromatograph coupled to a G2350A atomic emission detector (AED) to analyze carbon, sulfur, and nitrogen compounds in a gaseous matrix. The method addresses the need for timely and accurate analysis of pollutants like hydrocarbons, sulfur oxides, and nitrogen oxides from sources such as refineries and wastewater treatment plants.
