901303 Cytometer Technologies for Autonomous Platforms : Johnson Lab Coulter Counter This page last changed on Sep 13, 2013 by oreilly. Attendees: Johnson, Massion, Klimov, O'Reilly KJ: Want to keep cost cheap, less than $5K; want low power, suitable for profiling float deployment No moving parts Micro-electrode array exposed to external flow Could have programmable electrode spacing to vary sensitivity Probably don't need concurrent CTD Shape of electric field is complex TO: Would standard calibration beads with known size distribution help? How about adaptively driving which electrodes are paired as particle moves across surface? Hope for 5-200 um range - size spectrum Impedance spectroscopy
