    Direct atomic absorption mercury determination in tissues and biological samples

    INTRODUCTION Mercury and its compounds are highly toxic substances fo r humans. It occurs naturally and exists in various forms: elemental (or metallic); inorganic (e.g. mercuric chloride); and organic (e.g., methyl- and ethylmercury). These forms all have different toxicities and implications for health. Among naturally occurring mercury compounds, methylme rcury exerts a significant influence (neurotoxic action) on human health.

  • Determination of Mercury in Water Samples by HG-AFS

    Mercury and its sompounds are highly toxic materials and can be transferred into the human body via water; the concentration of mercury in water generally is very low. With the superior sensitivity of Aurora`s Atomic Fluorescence Spectrometer, the LUMINA 3300, direct measurement of mercury in water sample is possible.

    Mercury monitoring for ocean cruises

    Researchers at Battelle Pacific Northwest Laboratory used a Tekran 2600 on a 2009 ship cruise. Due to the low levels of mercury in water, Tekran provided them with a custom 2600 Event Table to pre-concentrate mercury from multiple samples to push the detection limit lower. When planning an ocean bound cruise, instrument dependability is a paramount concern. At sea, there is no possibility to return instrumentation to the manufacturer for quick repair. The Tekran 2600 has a well deserved reputation for dependability...

    RAPID ANALYSIS OF TOTAL MERCURY IN WASTE WATERS AND PROCESS WATERS WITH ELEVATED MERCURY CONTENT USING DIRECT PYROLYSIS TECHNIQUE

    A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes 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 determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages. The...
