Sodium determination is consistently becoming more important for the food industry. Conventional sodium testing methods are complicated and require expert user knowledge. In a live webinar on April 11th and October 3rd, METTLER TOLEDO presents a new analytical method dedicated to the simplified, yet highly accurate, determination of sodium.
It has long been known that too much sodium in the diet can be harmful to a person’s health. It is linked to hypertension, cardiovascular disease, and stroke. The pressure continues for food manufacturers to accurately determine, and subsequently reduce, the sodium content in their food products and to provide correct labeling. Accurate and efficient sodium determination is therefore of high importance to food producers.
Conventional Sodium Determination Techniques
Conventional techniques for direct sodium determination, like Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma Emission Spectroscopy (ICP), and Ion Chromatography (IC), require external calibration and elaborate sample preparation. Investment in mostly large devices is relatively high in comparison to other analytical equipment, and in-depth knowledge of operation is essential. Food companies often have to rely on external research labs, prolonging and complicating the entire quality control process.
Multiple Standard Addition Technique
Sodium determination using the multiple standard addition technique is performed by ion-selective sensors. As the membrane potential cannot be observed directly, the potential of the ion-selective electrode (ISE)…
