Direct desorption/ionization (no matrix) and matrix‐assisted laser desorption/ionization (MALDI) were tested for the analysis of four pesticides, aldicarb, aminotriazole, dinoterb and ioxynil, at the 0.1 μg/L level in water. Only MALDI provided good sensitivities, except for aldicarb. The most interesting result is that quantitative analysis of aminotriazole at the required level should be feasible using MALDI, which is not possible using standard methods, at the present time. © 1998 John Wiley & Sons, Ltd.
