That is the reason why conventional AFS and AAS methods include sample digestion by acids and require compressed gases such as argon or oxygen. This makes analysis more complicated and costly and extends analysis time. Sample pre-treatment can also increase measurement errors. The use of a RA-915M/RA-915M+ mercury analyzer with a PYRO-915+ pyrolytic attachment or RA-915F mercury ?nalyzer provides direct mercury determination in foodstuff, food/feed products and ...

Introduction A conventional standard method of total mercury det ermination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that ta kes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct dete rmination of mercury in process and waste waters contaminated with ...

INTRODUCTION Blood is one of the most complex substances for determination of the Hg content. At the same time, blood is the most important diagnostic medium used for monitoring the effect of Hg vapor on the human organism. In almost all the countries, personnel of mercury-involving production facilities are regularly examined for the Hg content in blood, which should not exceed 20–50 µg/l, whereas in the case of a person unexposed to mercury vapor the blood normally contains 1–3 µg/l of ...

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. ...

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 ...

In studying the planetary processes and makeup of the Earth (geology), geologists routinely analyze the composition of rock and mineral samples. Rapid elemental analyses for sodium (Na) through uranium (U) can be accomplished through the use of cost-effective, high-performance Energy Dispersive X-ray Fluorescence (EDXRF, XRF) instrumentation without destruction, digestion, or alteration of the sample. ...
