6.2.5 Solutions
The solutions to be used must, as usual, be defined in tiamo
TM
. Connect the Dosino of the 50 mL
Dosing Unit to MSB 1 of the 905, the Dosino of the 20 mL Dosing Unit (HCl) to MSB 2 of the 905, the
Dosino of the 10 mL Dosing Unit (EDTA) to MSB 3 of the 905 and the Dosino of the 20 mL Dosing Unit
(Auxiliary complexing solution) to MSB 4 of the 905. The user is automatically requested to save the
solutions – click on
. In order to ensure compatibility with the methods provided, they must be
named as described below.
