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 ...

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 ...

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 ...

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. ...

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 ...

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 ...

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. ...

Protect the heart of your Continuous Casting Machine. The CastCoat hard composite coating was developed by the advanced Castolin Eutectic workshop in Newcastle, UK, for steel industry applications in particular for coating continuous Caster copper mould plates, for more than 20 years. Tests have shown that the coating is tougher than any other copper mould plate coating available. It has a low coefficient of friction which helps reduce sticker alarms and the coating is inert to liquid steel and casting powders. ...

The fume ducts in the Steel Plants are exposed to high erosion wear or corrosion. Moreover, their internal walls are subjected to the impact of erosive particles transported at high speed by ventilation gas at high temperatures. In some applications, ventilation gas is also corrosive. Since decades, Castolin Eutectic has been the provider of choice for service, repair and preventive maintenance of heavy-duty and industrial process equipment. In Iron & Steel, protecting your industrial process equipment, fume ...
