| 摘要 |
The present invention comprises method and apparatus for the quantitative determination of particles in fluid. Apparatus of the invention comprises an emitter set of one or more light emitters, in combination with a detector set of one or more light detectors sensitive to the output of the emitters; during analysis of the sample, data from a plurality of signal paths between the emitter and detector sets are gathered. This information is subsequently evaluated by comparison with known data for different fluid particle contents. Some differentiation between different particles in a fluid sample are possible in many embodiments. Typical uses include analysis of milk and dairy fluids, blood samples, lubricants, suspensions of pigments, etc.
