Interfacing microfluidic chip-based chromatography with flame atomic absorption spectrometry for the determination of chromium(VI)
Abstract(#br)This work demonstrates the first study on interfacing of microfluidic chip-based chromatography to flame atomic absorption spectrometry (FAAS) for a simple and fast separation or preconcentration and subsequent determination of species. The developed low-cost polydimethylsiloxane microchip includes 12 microcolumns of conventional C18 (5\u003cce:hsp sp=\"0.25\"/\u003eμm) chromatographic particles, making the parallel chromatographic separation/preconcentration and the direct introduction of the effluent into the spectrometer possible.
