Gas chromatograms of pesticides and phthalate esters obtained by an automatic injection system are analyzed by a computerized gas chromatographic data system. The system described provides for simultaneous injection onto two independent columns equipped with individual detectors. The gas chromato-graphic output is processed by the computer into a report for each column listing the names the concentrations for compounds of interest. The system has sufficient sensitivity and reliability to allow routine detection of chlorinated pesticides at the picogram level and organophosphorous pesticides and phthalates at the nanogram level. This system is readily incorporated into methods currently recommended by EPA for pesticide residue analysis. Once the system is calibrated, 42 injections can be made without operator intervention. |
