A blood processing chamber (22) separates blood into constituents including a plasma constituent that includes a platelet volume. An optical monitor (98) detects the optical density of the plasma constituent and generates a first output indicative of the optical density. A processing element (100) integrates the first output relative to the volume of plasma constituent and generates an integrated output. The integrated output correlates to the platelet volume. A second processing element (72) generates a third output based, at least in part, upon the integrated output, which encompasses parameters for storing the platelet volume.

Chambre de traitement (22) de sang qui sépare le sang en ses constituants, dont un constituant plasma qui comporte un certain volume de plaquettes. Un moniteur optique (98) détecte la densité optique du constituant plasma et produit une première sortie indicatrice de la densité optique. Un élément de traitement (100) intègre la première sortie par rapport au volume du constituant plasma et produit une sortie intégrée. La sortie intégrée correspond au volume des plaquettes. Un second élément de traitement (72) produit une troisième sortie basée, au moins en partie, sur la sortie intégrée, qui comporte des paramètres de stockage du volume de plaquettes.
