The sample of biodiesel is weighed into a crucible and placed in a heating muffle furnace. Two temperatures are used in the heating program for the dry decomposition: the first temperature (250ºC) is maintained for 1 hour to dry the sample. After this the temperature is progressively elevated to 600ºC and maintained for 4 hours to eliminate the remaining organic material. ...

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 ...

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. ...

This method uses a suspension of ground plant material to directly measure the potassium concentration. It eliminates the usual steps of ashing and subsequent dissolution of the resulting ash. The method was compared to alternative methods such as chemical analysis and spectrophotometric methods. Collaborative studies using a range of samples gave a mean of 1.74% potassium by this extraction technique as compared to 1.75% by alternative methods. The standard deviation of an analysis in the two different sample ...

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. ...

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 ...
