REVERSED-PHASE HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHIC DATABASE OF RETENTION INDEXES AND UV SPECTRA OF TOXICOLOGICALLY RELEVANT SUBSTANCES AND ITS INTERLABORATORY USE

An HPLC identification system based on a 1-nitroalkane retention index scale and secondary retention index standards is described. The reten tion index values and spectral data for 383 toxicologically relevant c ompounds (therapeutic and illicit drugs, environmental toxins and endo genous compounds) are given. The retention data may be directly applie d in any laboratory using any reversed-phase, base-deactivated column, provided that the standardized procedure is observed.
