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 ...

FT-NIR spectroscopy in rapid detection of paprika adulteration sector
There is a long history of spice adulteration, which dates back thousands of years. The main incentive behind the adulteration is economic: either reduction of cost or increase in perceived value. Most adulterants are harmless, such as adulteration with products from non-authentic geographic origins. However, some adulterants are deadly. Paprika, as an example, can be adulterated with tomato skins and brick dust, but it can also be adulterated with lead oxide and carcinogenic chemical dyes, such as Sudan I dye. ...

Mercury determination in natural, surface, sea, drinking, bottled, mineral, and waste water by cvaas
Introduction Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l: 0.5 – Japan, Russia; 1 – Argentina, Australia, Brazil, China, EC; 2 ...

Flame Photometer for Measurement of Calcium in Biological Samples
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. ...
