3.1 Generation of Measurement Conditions
3 - 32

Rinse Replicate
Inputs the number of autosampler nozzle rinsing times
before pipetting. Usually, “1” (once) is input.
If carryover due to the previous sample is recognized,
increasing the number of rinsing times may be helpful.
The liquid properties of the rinse solution should be
matched with those of the sample.
Input will be accepted within 1 to 5.

Injection Speed
Specifies the sample aspiration and injection speed of
the autosampler.
The relationship between the specified value and the
aspiration/injection speed is listed in the table below.
Specification of “4” does not pose a problem usually.
However, the speed should be slowed as required for
pipetting of a highly viscous sample or the heating
injection described below.
Specification No. Aspiration/Injection Speed (

L/s)
1 2
2 6
3 19
4 30
5 60

Continuous injection
When measurements are made by the autosampler with
multiple samples (a sample solution and a chemical
modifier, etc.) injected in the cuvette, the samples are
continuously drawn all at once into the cuvette. For
details, refer to 5.4 “Continuous Sample Injection” in
Chapter 5.
NOTE : Depending on the order of sample injection, the nozzle
is immersed in the next sample and the sample in the
cup may be contaminated.
