3.1.2 Principles of Operation
The Reagent Pipette aspirates the Latex Reagent, which then move to a
Cell on the Reaction Table, where it is dispensed together with the Buffer.
Next, the Reaction Table Rotates and the Cell containing the Reagent
moves to the sampling position. The Sample Pipette aspirates a Sample,
which is then dispensed to the Cell. The Mixing Spatula then turns
counterclockwise to mix the Reagent and the Sample together.
The Cell containing the Reagent and the Sample moves to the detection
position after a period of time set under the measurement conditions, and
the first photometric measurement (IST
T1
) is performed. After another set
period of time, the second photometric measurement (IST
T2
) is
performed.
The amount of change in the Integrating Sphere Turbidity of the two
photometric measurements (ΔIST=IST
T2
-IST
T1
) is calculated by the
computer according to the calibration curve to output the measurement
result.
This series of actions is repeated to measure all samples placed in the
sample rack.
