More Information
Summary:A blood analyzing instrument comprises a single transducer for simultaneously measuring the DC volume, RF conductivity, light scattering and fluorescence characteristics of blood cells passing through a cell-interrogation zone. Preferably, the transducer comprises an electro-optical flow cell which defines a cell-interrogation zone having a square transverse cross-section measuring approximately 50 x 50 microns, and having a length, measured in the direction of cell flow, of approximately 65 microns. Un analyseur de sang comprend un seul transducteur pour la mesure simultanée des caractéristiques de volume CC, de conductivité RF, de diffusion de lumière et de fluorescence des globules sanguins traversant une zone d'interrogation de globules. Le transducteur comprend, de préférence, une cellule d'écoulement électro-optique qui définit une zone d'interrogation de globules possédant une section transversale carrée d'environ 50 x 50 microns, et une longueur, mesurée dans le sens d'écoulement des globules, d'environ 65 microns.
