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 ...

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 similar ...

INTRODUCTION At present, pharmacology, being an integral part of medical science, shows rapid development resulting in the discovery of ever growing number of new drugs and medicines. Hence, quality control and identification of drugs acquires vital importance as the number of counterfeited products inconsistent with Pharmacopoeia concurrently increases with the introduction of new numerous drugs. Identification of the drugs is necessary to reject the products that not only lack the required medicinal properties ...

Introduction: The presence of uranium in water causes radiological pollution as all uranium radionuclides decay by both alpha and gamma emissions. Chemical aspects of uranium toxicity include mainly nephritis and other renal diseases. Mentioned harmful features affect on humans even in low concentrations thus requiring sensitive analysis ...

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 ...

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 ...

Introduction : Analysis of soils, bottom and overburden sediments, rocks and ores for mercury content is one of the most common measurements in environmental pollution monitoring and geochemical exploration. Lumex Instruments proposes a rapid and precise method for direct mercury determination using RA-915 series analyzers based on atomic absorption spectroscopy with Zeeman correction of the background absorption (ZAAS). The thermoscanning option enables the identification of mercury species with varying binding ...

The Situation:Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil. These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often use once through cooling water systems. The cooling water is taken from lakes, rivers, or the ocean and circulated once through the plant to cool processes. Large volumes of ...

The Situation: California is currently facing one of the most severe droughts in recorded history. In order to mitigate the drought conditions, various water conservation measures have already been implemented, and others are being considered. One method under consideration is using the advanced treatment of produced water to make it available for irrigation. A major challenge to the success of this method is economically treating the produced water to achieve the quality mandated by California’s irrigation ...
