Abstract :
Low frequency electronic gating is proposed for the detection and sizing of cells, bacteria and colloidal particles in liquids. LF gating avoids the disturbing effects of electrolysis inherent to DC-operated systems and the poor sensitivity of HF gating. The technique is intended for continuous operation online, in chromatography-like experiments
