Hydrofluoric and nitric acid in etching baths

Titrando family
Titrating is just intelligent dosing. With the Titrando, dosing is carried out by a Dosino and Dosing Unit mounted directly onto the reagent bottle. This means that dosing does not occupy more space than the footprint of the reagent bottle.

The Dosino is equipped with state-of-the-art mechatronics. The Dosing Unit can be replaced in no time. It is intelligent, as it is equipped with a data chip containing all the necessary data about the reagent and the Dosing Unit that is required for the titration. This information is available to the Titrando.

Each Dosing Unit has a serial and a cylinder number and is supplied with an individual certificate.
 

 
AN-T-034 Hydrofluoric and nitric acid in etching baths

Determination of hydrofluoric and nitric acid in etching baths by potentiometric titration.

a) Determination of the total acid content using the combined Sb electrode and NaOH as titrant.

b) Determination of hydrofluoric acid using the F-ISE and the titrant La(NO3)3.

The concentration of nitric acid is then determined by calculation.
