IIT Research Institute (IITRI) has been subcontracted by GCA/Technology Division (GCA) to perform quality assurance checks on ambient air samples taken in the Love Canal area of Niagara Falls, NY. Specifically, the subcontract requires the quantitative analysis of nine QA/QC Tenax cartridge samples for nine organic compounds as well as perfluorobenzene and octafluorotoluene, and the qualitative identification of chloroform, if present. Characterization and quantification of the components in the cartridges are carried out by high-resolution gas chromatography/mass spectrometry/data system. Appropriate standardization and quality control measures will be performed as required.
