There are several challenges when screening for hazardous chemicals in Homeland Security and environmental samples. The methods for analyses must rapidly and accurately identify the specific toxic agents involved, possess a high dynamic range and have low detection limits. In a sample that was 2 ppm each analyte in a matrix of 100 ppm of gasoline, the Agilent ChemStation found all but two of the compounds. Those two compounds had qualifier ions out of range due to interferences from the matrix. AMDIS successfully found all 14 compounds. Also, with the exception of compound 8, all of the analytes were clearly visible above the matrix responses on the ECD chromatogram.
