title: Analysis of mutagenic imidazo[4,5-f]quinolines and -quinoxalines (IQ compounds). Comparison of electrochemical and ultraviolet detection.
abstract: Two synthetic imidazoquinolin-2-amines (IQ and MeIQ) and two imidazoquinoxalin-2-amines (MeIQx and 4,8-DiMeIQx), all known potent mutagens, have been separated by reversed-phase HPLC and detected by two methods - UV detection and electrochemical (EC) detection. The limits of detection were found to be 2.5 pmoles for UV detection and 0.5-1.5 pmoles for electrochemical detection.
