Abstract

This invention relates to a small, hardy, less expensive, easy-to-operate electrokinetic instrument developed specifically for rapid sterility testing. The electrokinetic apparatus comprises a separation pathway; an electrical supply; two electric contact buffer pools; a sample solution inlet; a blocking agent reservoir; laser(s); and a photodetector. It utilizes a segment of dilute cationic agent to temporarily reverse the migration direction of the microbes, and another segment of solution containing a 'blocking agent' to hinder the microbe migration and focus them into a narrow zone.
