METHOD AND DEVICE FOR CONTINUOUS MEASUREMENT OF CONCENTRATION OF MICROBE CELLS IN SUSPENSIONS Russian patent published in 2006 - IPC G01N15/06 

FIELD: optical analyzers; particle laser analyzers; measurement technology.

SUBSTANCE: method and device can be used for continuous real-time scale measurement of concentration of microbe cells (density of biological mass) in liquid fermenters or similar reservoirs containing cell suspension. Number of cells in suspensions is determined continuously on the base on measurement of intensity of light dissipated by cells. Determination is based upon usage of calibration data received while measuring light dissipation in suspensions with known concentration of cells of that type which would be used in samples to be analyzed. Intensity of dissipated light is measured by photodetectors mounted at different angles to radiating light in such a manner that detection range equals to 0-180°. Gas bubbles are preliminary removed from suspension before delivering it measurement dish. Concentration of microbe cells can be determined within 0,01-100 g/l range in suspensions, including samples from fermenter.

EFFECT: improved truth of measurement.
