Abstract
(EN) An analyzer having an inner chassis surrounded by a housing includes sample and dilution probes, a mixing housing including first and second mixing chambers, a flow cytometer including a flow cell, and sample and sheath pumps configured to perform first and second pluralities of tasks, respectively. The first plurality of tasks includes: aspirating sample into the sample probe, dispensing sample from the sample probe into the first and second mixing chambers, delivering first sample-dilution fluid mixture to the flow cell, and delivering second sample-dilution fluid mixture to the flow cell. The second plurality of tasks includes: dispensing sheath to the flow cell in cooperation with the delivery of the first sample-dilution fluid mixture to the flow cell, and dispensing sheath to the flow cell in cooperation with the delivery of the second sample-dilution fluid mixture to the flow cell.
(FR) Un analyseur comportant un châssis interne entouré par un boîtier comprend des sondes d'échantillon et de dilution, un boîtier de mélange comprenant des première et seconde chambres de mélange, un cytomètre en flux comprenant une cellule à flux, et des pompes à échantillon et fluide de gaine conçues pour effectuer des première et seconde pluralités de tâches, respectivement. La première pluralité de tâches consiste à : aspirer l'échantillon dans la sonde d'échantillon, distribuer l'échantillon de la sonde d'échantillon dans les première et seconde chambres de mélange, fournir un premier mélange de fluide de dilution d'échantillon à la cellule à flux, et fournir un second mélange de fluide de dilution d'échantillon à la cellule à flux. La seconde pluralité de tâches consiste à : fournir un fluide de gaine à la cellule à flux en coopération avec la distribution du premier mélange de fluide de dilution d'échantillon à la cellule à flux, et fournir le fluide de gaine à la cellule à flux en coopération avec la distribution du second mélange de fluide de dilution d'échantillon à la cellule à flux.
