As demand grows for accurate nutritional labelling and improved food quality control, thermometric titration is proving to be a rapid and reliable approach for the direct determination of sodium in food products. Unlike traditional chloride-based methods, which assume all sodium originates from sodium chloride and can thus lead to major inaccuracies in complex food matrices, thermometric endpoint detection measures sodium directly, delivering more representative results.
The technique requires minimal sample preparation, no sensor calibration and only limited maintenance, making it an efficient option for labs. Additionally by measuring the temperature change generated during the sodium precipitation reaction, thermometric titration can provide accurate results in less than two minutes.
Available on Metrohm’s OMNIS Titrator platform, the method also supports parallel measurements and full automation, helping food lab increase throughput whilst maintaining confidence in their data.
