Number of
static rinses If a Sample Changer is in use, enter the desired number of static
rinses to be carried out before each sample run of a SAC sequence.
During a static rinse, the electrodes are dipped for a time (selectable
between 0 and 30:59 min:s,
see "Rinse time", page 211 ) into a
beaker filled up with a rinse or conditioning solution.
These rinse beakers are located:
• on the 1, 2 or 3 last positions of the SAC80 turntable,
• on the RINSE 1, RINSE 2 or RINSE 3 dedicated rinse positions of
a SAC90 tray,
• on the last 1 or 2 available positions of the SAC850 tray,
• on the 1 or 2 dedicated rinse positions of the SAC950
reconditionning beakers extension.
Enter in:
Setup menu > Configuration
Range available:
• 0, 1, 2 for a SAC850 or SAC950.
If you have allowed the dynamic rinses to occur in previous beaker
except 1st in Rinse 2, then only one beaker will remain available for
static rinses (Rinse1 beaker).
Refer to "Dyn. rinse", page 99 .
• 0, 1, 2 or 3 for a SAC80/SAC90
Refer to User’s Guide of the sample changer used (part no.: D21T002
for a SAC90, D21T013 for a SAC80, D21T085 for a SAC850 or
SAC950).
Number of
solutions Available if Calibration request = Yes
Number of ISE standards to be used for the ISE electrode calibration.
Work with at least 3 standards to calculate the electrode C
0
concentration which represents the experimental detection limit of the
ISE electrode regarding the ion under study.
Work with at least two standards to calculate the electrode sensitivity.
If only one standard is used, only the E
0
electrode standard potential
will be calculated.
Refer to "Direct ISE measurement method - definition", page 95 .
