摘要:We present the use of impedance monitoring to determine the geometrical characteristics and the ionic concentration of droplets in a microchannel. A compact impedance monitoring system is developed based on an embedded computer that can provide an adjustable excitation signal from 2 KHz to 2 MHz. Aqueous droplets are continuously formed by hydrodynamic focusing and then directed into a primary channel for monitoring with embedded electrodes in a microfluidic chip. With the monitoring system, the correlation between the electrical amplitude and the ionic concentration in droplets is investigated and the correlation coefficient is 0.98.
