This method reduces or removes potential interference from sodium, potassium and phosphates normally present in serum and urine by diluting the samples with a diluent containing ethylenediaminetetraacetic acid ...

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. ...

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. ...

Take a sample of lettuce and remove any soil but do not wash the plant tissue as doing so may reduce the number of ions in sample. ...

The calcium content of aqueous solutions of deoxyribonucleic acid (DNA) and deoxyribonucleoprotein (DNP) cannot assayed directly because of interference effects. An acid extraction procedure enabled direct measurements of calcium in DNA and DNP, or a standard addition technique was used at higher ...

Sodium chloride is an essential ingredient of all processed foods; it is needed to enhance flavour and increase shelf life. In many processed foods, additional sodium is added as a flavour enhancer; potassium and calcium are also naturally present but not normally used as processing ...

Several different techniques can be used for sample digestion and extraction of sodium and/or potassium: oven ashing, perchloric acid ashing, extraction by boiling and acidification with HNO3 as well as extraction by homogenisation in 2% trichloroacetic acid (TCA). ...

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 ...

Raman spectroscopy is an analytical technique which can be used both quantitatively and qualitatively. This application note details the quantitative use of Raman spectroscopy to determine ethanol content in samples of whisky. Qualitatively, Raman ...

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 ...

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. ...

As lead acid batteries are charged, minute quantities of hydrogen (H2) gas are produced. Normally, the amount of hydrogen generated during charging is not of a sufficient quantity to cause concern. There are instances however, where for various reasons, hydrogen may accumulate to create potentially hazardous gas ...

Bacterial indicators are enumerated in surface/recreational waters to assess the presence and level of fecal contamination and thus determine the potential for disease. Total Coliforms and E. Coli are widely used in regulatory monitoring of surface waters. E. Coli is specific to fecal sources and is therefore recommended as the main indicator of fecal pollution. E. Coli is present in extremely large numbers in the feces of all mammals, and does not multiply appreciably in the environment outside of its host. The ...

IUL’ laboratory blender, known as Masticator, carries out a profound homogenization which makes it possible to obtain a sample perfectly representative of the food, drug, cosmetic, or any kind of material that has to be ...

Particle size is a geometric characteristic that is usually assigned to material objects with sizes ranging from nanometers to millimeters. There is a wide variety of real systems that contain particles within this size range. These systems are generally polydisperse, meaning that the particles in a particular sample vary in size. Therefore, in order to adequately characterize such systems, it is not sufficient to simply determine a single particle size. We must instead determine the system’s particle size ...
