PremiumDetermination of the mercury concentration in naphtha
Introduction
The mercury concentration in crude oil and petroleum products can vary in a wide range of less than 0.1 ppb to dozens ppm. Direct mercury determination in crude oil and petroleum products at the range above 5 ppb is covered by ASTM D7622-10(2015) "Standard test method for total mercury in crude oil using combustion and direct cold vapor atomic absorption method with Zeeman background correction". Mercury determination in naphtha and light petroleum products (condensate, gasoline and diesel fuel) at a level below 5 ppb is a vital problem for the oil refining and petrochemical industry. Complex organic matrix impedes conventional quantitative analysis for mercury.

Determination of total mercury content in blood by cvaas
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 Hg.

Determination of heavy metals in food
This analytical procedure is intended for measuring the content of the elements (cadmium, lead, arsenic, tin, chromium and mercury) in the samples of food products by atomic absorption spectrometry with electrothermal atomization using an “MGA-915M” Graphite Furnace AA Spectrometer.
The method is based on measuring resonance radiation absorption that occurs when the radiation passes through a layer of atomic vapor in the electrically heated graphite furnace of the “MGA-915M” AA spectrometer. The concentration of the elements is determined from the integrated analytical signal and is calculated using a preset calibration graph. The samples of food products are digested prior to analysis in accordance with standard methods.
