Flow-through microfluidic digital impedance detection
Abstract
A Teflon coated flow cell has been designed for detection of analyte concentration and liquid identification of solvents. An AC voltage is applied across the flow cell to generate a current that is displayed in real time and used in solvent analysis. Experimental methods include injecting different concentrations of analytes in a flow path and analyzing current peaks that result as analytes enter the cell. The method provides a highly sensitive …
