Fast impedance spectroscopy for characterization and counting


Microfluidics benefits greatly from electrical impedance measurements when it comes to measurement speed and sensitivity. In this presentation, we will show how to build a microfluidic electrical impedance spectroscopy platform and include measurement results from an operating microfluidic system. A highly accurate and stable flow rate, critical for most microfluidic applications, is achieved using the LineUp series. The EZ drop can smoothly generate water-in-oil droplets with a wide range of sizes. On the detection part, thanks to the differential current measurement scheme, the HF2LI Lock-in Amplifier can resolve individual flow processes within a 5 µs timeframe, with clearly distinguishable peaks for droplets and microbeads in different sizes. Simultaneous multi-frequency measurements further unveil a full picture of their dielectric properties.
