3 System Principles
3.1
Introduction
The analyzer uses the electrical impedance method to determine the count and size
distribution of RBC, WBC and PLT, and uses the colorimetric method to determine HGB. Based
on the above data, the analyzer calculates other parameters.
3.2
Analyzer Workflow
We have defined the whole operation workflow of the analyzer by its major functions:
reagent system, sample loading and distribution, sample preparation, sample measurement,
signal processing, parameter analysis, status monitoring, scheduling control and information
processing, man-machine interface, power as well as cleaning and maintenance. The
relationships between the functions are illustrated as below:
The scheduling control and information processing module coordinates and regulates other
functional modules to work by defined process and requirements, so as to ensure the
completing of sample measurement, the ultimate task of the analyzer.
