Determining the amount of tin in tinned
food
Differential pulse anodic stripping voltammetry (DPASV) in combination with a hanging mercury drop electrode (HMDE) provides an analysis method for determining the concentration of tin in canned food
Canning food is a good method of preservation which uses no chemical preservatives and is therefore widely used Usually cans consist of tin plate, which is tin coated steel
Tin is necessary to prevent the iron from being corroded by the canned food.
Unfortunately tin itself can slowly transfer into the food.
Lead, which was used with tin until lately as a solder (also for cans), can also be determined with the described method from Metrohm.
A specification between Sn(II) and Sn(IV) is also possible.
The anodic stripping voltammetry can be carried out on a 797 VA Computrace enriched with the unbeatable Dosino technique for liquid handling.
For convenience, the methods for the tin and lead determination are already implemented in the Metrohm 797 VA Computrace. Request a free brochure from Metrohm UK ...
