We demonstrate a novel method to detect and characterize the size and number of Wollastonite particles using microfluidic impedance cytometry. The fabricated device which consists of gold electrodes micro-fabricated in a microchannel is capable of detecting particles >1 micron. Particle characterization is often carried out across a wide range of industries and is a critical parameter in the manufacture of various products to help improve the characteristics, performance or quality of powders or particles. There are a number of commercially available particle characterization techniques like laser diffraction, dynamic light scattering, electrophoretic light scattering, automated imaging, sedimentation etc that can be used to measure particulate samples and each has its relative strengths and limitations-there is no universally applicable technique for all samples. Our approach uses electrical impedance spectroscopy which measures the change in impedance as the particles in suspension pass through the sensor. It is a highly precise, low cost alternative for particle size characterization with a smaller footprint offering quick analysis time and is suitable for relatively broad range of particle sizes.
