This poster looks at the possibility to modify the existing EPA Method to meet California`s rigorous public health goal (PHG) of 0.02 μg/L. After optimizing instrument settings and method parameters, a method detection limit (MDL) of 0.01 μg/L is obtained. While the used microbore column guaranteed precise and accurate analytical results within less than six minutes, the applied flow-through reactor and the UV/VIS detector allowed to significantly enhance the efficiency of the post-column reaction.
