Metrohm has reported how its Titrando range of automated titrators can perform analysis of salt in food products without the need for nitric acid.
The salt level in food products is an increasingly important factor to determine, whether it be for health reasons or simply for taste.
The analysis for salt is routinely performed by companies on many products, for example, cheese, dairy products, sauces, soups, pasta, and jams.
The analysis to date has involved various methods, the most common being the precipitation titration using silver nitrate as titrant to a mV end point.
The problem with this manual titration is that the result is variable and it is an ineffective use of analyst's time.
With the Metrohm Titrando range of automated titrators, this analysis can be performed accurately and reproducibly without the need for nitric acid.
Analyst's simply place a sample in a beaker, add some warm distilled water and press 'start'.
The instrument then performs the titration automatically and provides a result on the screen, printed out or on a PC within two minutes.
With the addition of an autosampler, further time and money can be saved.
