In Korea, arsenic contaminants from trash yards and dead mines are becoming an issue. These contaminants dissolve in to the ground water and endanger water supplies for home, agriculture uses. We present using capillary electrophoresis and its applications to analyze arsenic compounds in the ground water with high efficiencies. Although capillary electrophoresis is suitable for aqueous sample analysis, In case of real samples, applications of capillary electrophoresis mass spectrometry with various enhancing methods still have some obstacles, such as excess amount of salt and other abundant residues. First we applied electrokinetic supercharging, consisting of transient isotachophoresis and field amplified sample injection, to overcome these obstacles. Then, we modified electrospray head unit to control flow in the capillary, which helps to conduct counter flow electrokinetic supercharging and online liquid microextraction. This poster presents the work of flow that approaches to analysis of arsenic contaminants.
