Optical flow cell for measuring size, velocity and composition of flowing droplets
Optical flow cell for measuring size, velocity and composition of flowing droplets
Here an optical flow cell with two light paths is reported that can accurately quantify thesize and velocity of droplets flowing through a microchannel. The flow cell can measure the timetaken for droplets to pass between and through two conjoined light paths, and thereby is capable ofmeasuring the velocities (0.2–5.45 mm/s) and sizes of droplets (length > 0.8 mm). The composition ofthe droplet can also be accurately quantified via optical absorption measurements. The device hasa small footprint and uses low-powered, low-cost components, which make it ideally suited for usein field-deployable and portable analytical devices.

Abstract
Here an optical flow cell with two light paths is reported that can accurately quantify thesize and velocity of droplets flowing through a microchannel. The flow cell can measure the timetaken for droplets to pass between and through two conjoined light paths, and thereby is capable ofmeasuring the velocities (0.2–5.45 mm/s) and sizes of droplets (length > 0.8 mm). The composition ofthe droplet can also be accurately quantified via optical absorption measurements. The device hasa small footprint and uses low-powered, low-cost components, which make it ideally suited for usein field-deployable and portable analytical devices.
