Particulate matter analyzing apparatus and method |
摘要 |
A method and apparatus for jetting a measured volume of a suspension of particulates such as blood cells or colloids into a single fluid-primed incompletely partitioned transducer chamber in such a way that the dynamic relationship between the priming liquid and the inflowing jet imparts to the suspended particulates the properties of a stable stream line monofile which reliably traverses one or more particulate-identifying and/or analyzing sensing zones. Said transducer chamber has one or more of the following three sources of energy for moving the contained fluids: an easily maintained non-critical pressure differential between the suspension inflow port and an exit line, potential energy stored within the transducer chamber during the priming step, a pump mechanism to propel particulate-free fluid. The measurement period in all such transducers may be defined by monitoring the volume of either the inflowing or displaced outflowing liquid.
