Mercury monitoring for measuring mercury content in hair
Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then ...

Determination 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 ...

Activated carbons solutions for flue gas & mercury sector
In many industrialized nations it is common practice to use incineration methods for waste disposal. There are also ways to recover energy from the process. However, operating an incinerator requires strict adherence to environmental regulations. Hazardous, clinical and waste to energy incinerators can benefit from our EcoSorb range of activated carbon. Specially designed to adsorb unwelcome airborne compounds from flue ...

Mercury monitoring for isotopic abundance by the ICP-MS
Studies of real-world ecosystems are very complex. Mercury species inter-conversion as well as mercury deposition and evasion are constantly occurring. One technique to help sort out the processes is to trace reactions using natural Hg isotopes. Either by enriching a system with a particular isotope or determination of isotopic ratios as a technique of source identification, isotopes are a powerful tool for investigation. The Tekran 2600 Total Mercury and Tekran 2700 Methyl Mercury systems are designed to couple ...

Rapid analysis of total mercury in waste waters and process waters with elevated mercury content using direct pyrolysis technique
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 mercury without digesti on or any other sample ...

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 ...

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 ...
