Flame Photometer for Measurement of Potassium and Sodium in Bread
Bread contributes about one-sixth of daily salt intake and is used to improve flavour and texture. The amount of sodium in bread can differ significantly, depending upon brand and type of grain used, ranging from 592mg/100g to 748mg/100g. The level of sodium in bread is primarily due to the amount of salt added to the dough during manufacture. The amount of potassium is determined by the type of flour and the washing and bleaching operations during cereal processing. Bread does not make a significant contribution ...

Flame Photometer for Measurement of Trace Elements in Biodiesel
These methods are adapted from methods for the determination of sodium and potassium in fatty-acid methyl ester samples. The sample is diluted with an organic solvent (xylene, cyclohexane or petroleum ether) plus a stabiliser. The calibration standards which have a similar matrix to the prepared sample solutions, are prepared from sodium and potassium organometallic salts which are dissolved in a solution of xylene with a stabiliser. These European Standards specify a method for the determination of potassium of ...

Flame Photometer for Measurement of Potassium and Sodium in Wine
Wine is of particular interest nutritionally because it is typically low in sodium and relatively high in potassium. Sodium is the predominant cation in breakfast cereals, at levels reaching 8mg/g. Potassium and calcium also vary, particularly in wheat-based products and those enriched with milk products or calcium ...

Determination of Additives in Beverages using Ascentis Express Columns
Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. Dilution followed by direct injection into an HPLC is typically suitable. In this article we present two beverage ...
