    Analysis of Herbicides in Drinking Water

    Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases...

    Analysis of Isocyanates Using the ASSET™ EZ4-NCO Dry Sampler

    Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in...

    Improved Reproducibility and Reduced Sample Preparation Time for the HPLC Analysis of Aflatoxins in Raw Peanut Paste

    The US FDA and international regulatory agencies have set contamination levels for aflatoxins in animal feedstuffs. Since Aspergillus may infect commodities pre-harvest, during storage or during processing, monitoring for aflatoxins in associated agricultural commodities at all stages of production is requisite. Field screening methods exist that are adequate to estimate contamination levels for aflatoxins. When additional confirmation or quantification is desired, chromatographic laboratory analysis is often...

    Hazardous waste treatment solutions for chlorine industry

    The mercury cell process is a formerly widely-used production technique for the production of chlorine and caustic soda. The liquid metal, mercury, acts as cathode (negative pole) in this process. In the past, the loss of mercury during the process (to air, soil and water) led to serious health and environmental problems. Therefore, most European chlorine producers have decided to phase out the mercury cell process by 2020. Nevertheless, even today, almost 6000 tons of mercury is used per year for chlorine...

    Phosphorimetric determination of uranium in water

    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 methods.

    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...
