Abstract

A method is described for the determination of residues of the antibiotic chloramphenicol in biological samples. The method is based on gas chromatography/negative ion chemical ionization mass spectrometry and uses (37Cl2)chloramphenicol as internal standard. Selective ion monitoring of four analyte-specific ions enables the determination of chloramphenicol levels in urine of 3 micrograms l-1 with a coefficient of variation of 8%. The limit of detection of the method is 0.1 p.p.b. for urine, muscle and egg.
