Automated sodium determination in various foods with 859 Titrotherm
|
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.

AB-298 Automated sodium determination in various foods with 859 Titrotherm
|
In an acidic solution (containing NH4F * HF, Al(NO3)3 / KNO3) sodium forms NaK2AlF6 which precipitates in an exothermic solution. Several foods were analyzed, namely bouillon, gravy, tomato ketchup, corn chips, pretzel sticks as well as crackers. The reproducibility of the results was good. After weighing in and adding solutions, samples were crushed with a polytron to ensure homogeneity in the measuring solution. Relative standard deviations were between 0.08% and 3.75%.
