Abstract
This invention relates to an apparatus, method and system for directly obtaining the optical density of a dynamic biological system over the wide operating range and a wide range of organism mass, compensating for the primary interference factor, agitation and gas bubble formation, and thereby obtaining a on-line real time monitoring of cell density to follow the product concentration and progress of the biological reaction system.
