The most important ions which naturally occur in plant tissues are sodium, potassium, calcium, magnesium, nitrate, sulphate and phosphate. A sample of 5 g of oven-dried plant material contains on average, 25 mg calcium, 9 mg magnesium, 80 mg potassium and 3 mg sodium. The recommended method for the measurement of calcium is to precipitate the calcium as an oxalate, the precipitate is then dissolved and measurement taken from the resulting solution. Sodium and potassium may be measured directly following an ashing ...

Commercial cereals vary considerably in composition, both in their formulation and the ingredients added to enrich these products. 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 salts. ...

A number of methods have been reported for the measurement of calcium in biological materials by flame photometry or titration. This method employs trichloroacetic acid (TCA) to precipitate the proteins and has been found to be adequate to extract all of the calcium from tissue samples. Sodium, potassium and phosphate caused no significant interference and calcium concentration in the range of 0 to 2 µg/ml is readily determined. ...

The Photovolt Aquatest 2010 moisture analyzer provides rapid, accurate, and convenient low level moisture analysis ranging from low ppm to pure water with maximum isolation of solutions from atmospheric moisture. With a range of 1 ppm to 1,000,000, typical applications include low level moisture applications for liquids and dispersed solids, pharmaceutical samples, lubricating oils, chemicals and solvents, resins, lyophilized samples and plastics. The Department of Defense Naval Air Systems Command (NAVAIR) ...

The effect of potential interference from other constituents of sea water was studied, including sodium, chloride and potassium. It was found that pre-concentration of the sea water was not necessary prior to analysis. A filtration of the sample was only necessary if sample contained suspended material. ...

In most cases, it was found that flame photometry was well suited for the determination of sodium, potassium and calcium in fresh fruits, using the wet ashing technique as given below. There are significant differences in the composition between different varieties of the same fruit, although these differences are not usually considered to be nutritionally ...

A wide range of sample acquisition and filtration systems are available to prepare even the most difficult of samples for reliable on-line analyser measurement. The correct choice is often critical to prevent analyser blockage and optimise performance. Cross Flow Filtration The PPM cross flow filter, is a simple in-line device used to protect an analyser from ingress of solids, for applications where sample quality is generally good but occasionally suspended solids may be present. The stainless steel filter ...
