At the 5
th
cycle after the R1 dispense, sample tray rotates to transfer No.1 sample
cup/tube to the sampling position. Sample probe moves above the sample cup
then goes down.
*) Sample probe also has level sensing function, and stops at the sample level.
The designated amount of sample is aspirated by sample pump.
↓
Then sample probe moves above No.1 cuvette and goes down to the R1 reagent level
in the cuvette, and dispenses sample. After the dispensing, probe goes up.
↓
At the next cycle, the cuvette is moved to the mixing station-1, where R1 and
sample are mixed by MU-1, mixing unit.
This mixing is repeated in the next cycle, two times in total.
↓
Sample probe moves to probe washing pot and both inside and outside are washed
by de-ionized water, there. After that, residual water droplets are wiped out.
↓
After the R1 and sample are mixed, optical measurement starts. When reaction
tray rotates and the cuvette passes the optical measurement position, light
absorption data of 12 wavelengths are measured.
↓
After 5 minutes of R1 dispense, the cuvette moves to R2 dispense position, the same
position as R1 dispense, then R2 is dispensed by R2 probe, which has same function as
R1 probe. After the dispensing, R2 probe goes up.
↓
At the next cycle, the cuvette is moved to the mixing station-1, where R2 and
reaction liquid are mixed by MU-1.
This mixing is repeated in the next cycle, two times in total.
↓
R2 probe moves to probe washing pot and both inside and outside are washed by
de-ionized water. After that, residual water droplets are removed.
↓
After 4 minutes of R2 dispense, the cuvette comes to the mixing station-2, where the
particles in reaction liquid are dispersed again by MU-2. (Mixing before the
measurement is done by request.)
↓
After 10.7 minutes of sample dispense, reaction liquid in the cuvette is aspirated out
by the No.1 nozzle of the cuvette washing unit and transferred to the waste
reservoir, outside of the system.
