英文摘要	a method has been developed for peak identification of pcbs in gc with ecd detection under different temperature programs and isothermal conditions on two commonly used columns (db-5 and db-1701). this was achieved by means of accurate calibration of retention times based on the concept of the relative retention index p-i and retention times of the selected pcb internal standards. the p-i was calculated from the predicted retention times with the database of the retention parameters (a, b) and the migration equations. through comparison of the calibrated and experimental retention times of pcbs in technical samples, it was shown that the developed method was effective for correct pcb comprehensive, quantitative, congener-specific (cqcs) analyses.
