The method is based on the direct injection of 100 mu L of centrifuged water sample, without any other sample treatment. Very good method detection limits (0.014-0.44 mu g L-1) and excellent intra and inter-day precision (,RSD,% values in the range 1.8-4.4% and 2.7-5.7%, respectively) were achieved, with a total analysis time of 20 min per sample.
