Priority of Carry-over Washing

On concurrence of multiple carry-over washing timings, priority is given on the principle
below.
(a) Cell washing > probe washing
When the cell used for reagent probe washing requires washing, priority is given to
cell washing. On this occasion, probe washing is carried out after cell washing.
However, when use of the detergent at the same reagent position is specified for both
reagent probe washing and cell washing, the reagent probe washing step can be
substituted by the cell washing process. Therefore, only the cell washing is carried
out omitting the reagent probe washing.
(b) As for sample probe washing and cell washing, priority is given to cell washing.
(c) For sample probe washing and reagent probe washing, priority is given to sample
probe washing.
(d) When reagent probe washing R1, R2 or R3 and cell washing become necessary
simultaneously with the same cell, the next cell can be used for preventing overflow if
the total volume in a cell exceeds 540 µL.
