analysis with an automated system.
• Brightener determination (CVS, MLAT), automated
• Conditioning (Cu VMS), automated
• Suppressor determination (CVS, DT), automated
The templates already establish t h e bas ic s eq u e nc es fo r the
different applications, the use of 800 Dosinos for automatic
dosing as well as the calculation of the result and the
application of a sample changer and pumps to process a
sample series. However certain commands and settings
have to be adapted to the used hardware and the
requirements of the specific application.
For a step by step description please see the Tutorial
chapter «6.2 Methods for the automated determination».
The following commands have to be adapted:
4.1.1. Measuring commands

6. Remarks
stored separately in a vial filled with deionized water (KCl
solution, in case KCl is used as bridge electrolyte), so that
the reference electrode immerses at least to the rim of the
electrolyte vessel.
6.5. Waste container
The waste container must not be closed completely. For
pressure balancing in the waste container, keep at least one
opening unsealed. Overpressure would lead to a
malfunction of the drain pump.
6.1. Single additive setup
If the system is only used for suppressor or brightener
determination the unused port at the T connector
(6.2744.290) has to be closed with a threaded stopper
(6.2744.060).
6.2. Combination of applications
The determination of suppressor by dilution titration (DT)
and the determination of brightener by modified linear
approximation technique (MLAT) can also be combined in
one series.
6.3. Storing dosing units
When the dosing units are not used (during the night, over
the weekend) the dosing cylinder has to be rinsed with
water. Otherwise elemental copper can be formed or
additives can precipitate between the valve disk and the
distributor disk or in the tubings. A blockage can damage
the 800 Dosino. Emptying the cylinder and filling it with
water is sufficient to prevent a blockage.
6.4. Storing electrodes
When the electrodes are not used (during the night, over the
weekend) the electrodes should be thoroughly rinsed.
