OPERATION PRINCIPLES
SAMPLE FLOW

10. The unit does the WBC differential in the triple transducer module (TTM) at the flow
cell aperture.
Sample pressure to the mixing chamber pushes the sample through the flow cell for the
diff analysis. See Figure 3.10.

11. The cycle finishes:
r
The mixing chamber drains into its waste chamber.
r
The CBC baths drain into the waste chamber.
r
The unit cleans the baths and flow cell.
r
The waste chambers drain.
Retic Sample Flow
Placing the instrument in the Retic Mode allows the sample to flow directly to the mixing
chamber and flow cell of the triple transducer module (TTM). When in this mode, the sample
MUST be manually diluted and prepared before being aspirated by the instrument.

CAUTION
Using undiluted whole blood can clog multiple components of the instrument and might require
a service call to clean the components when the HmX Hematology Analyzer is in the Retic Mode. Manually
dilute the blood before introducing the sample to the instrument for aspiration when it is in the Retic Mode.
