Particle analyzing apparatus and method of moving particles in suspension through such apparatus |
摘要 |
A particle analyzing apparatus and method of moving and counting particles in suspension through such an apparatus. The particle analyzing apparatus comprises a particle counting device wherein particles in suspension are caused to be moved through an aperture whose effective impedance is changed with the passage of each particle therethrough and a fluid connection means for drawing a quantity of the suspension through the aperture, including a source of vacuum. The source of vacuum comprises a bellows having an end, and a constant force means connected to the end of the bellows means.
