Development of a new hybrid technique for inorganic arsenic speciation analysis by microchip capillary electrophoresis coupled with hydride generation microwave induced plasma spectrometry

► The successful interfacing of a microchip based CE hydride generation system to MIP-OES. ► Inorganic arsenic speciation in 70 s, within an 26 mm long separation channel. ► The detection limits for As(III) and As(V) are 3.9 and 5.4 ng mL-1, respectively. ► Sample volume of 25 nL.
