✦ Synopsis

The potential of unnrersal cahbratlon usmg capdlary gas chromatography combmed with atonuc enusslon detection was evaluated for several chlorme-and sulphur-containing compounds of environmental interest The elemental responses obtamed for C, H, Cl and S were found to be affected by the molecular structure Rapid determination of several analytes was accomphshed using a single calibration graph based on one randomly selected reference compound, but lo-30% errors relative to the actual concentrations were observed m several Instances The results were sigmficantly improved by usmg reference compounds urlth structures sunllar to those of the analytes of mterest The practical utility of umversal calibration IS illustrated by the determmatlon of pestlcldes m stomach 011 deposits from birds hvmg m Antarctrca
