Atmospheric elemental mercury (Hg), although present only in trace amounts, has been established as a significant source of Hg to aquatic environments. Mercury and most of its derivative compounds are metabolic poisons that bioaccumulate in aquatic food chains, ultimately reaching concentrations capable of causing neurological and reproductive damage in terrestrial as well as aquatic organisms. Atmospheric mercury deposition has also led to accumulation in forest soils. This application note demonstrates the measurement of mercury in atmospheric air, via collection tube, using direct mercury analysis.

Design features incorporated into the HPX Series inert hotplates give unmatched temperature uniformity across the heating surface, providing greater control over sample digestion and evaporation. Incorporating more cartridge heaters than are typically used in inert hotplates reduces temperature variability across the heating surface. In addition, the use of premium, ISO-molded, low-porosity graphite gives superior thermal conductivity and also allows for a high-integrity PFA coating which protects the heating block, prevents corrosion and contamination, and extends operating life.

Mercury is dangerous to both natural ecosystems and humans because it is highly toxic, with the ability to damage the central nervous system. To prevent mercury poisoning, it is necessary to accurately quantify total mercury in coal so that emissions into the atmosphere may be carefully controlled. This application note demonstrates direct mercury analysis in coal by thermal decomposition.

The ability for Milestone’s Ethos UP to operate at high temperature and pressure, along with real-time temperature monitoring allow for superior digestion of the most difficult pharmaceutical samples. Together with our unique vent-and-reseal technology, loss of precious volatiles is minimized, resulting in excellent recoveries of trace metals and highly accurate ICP analysis.

Recently, the compact MAGPRO’s maximum voltage was increased from 60 kV to 70 kV while maintaining the same size profile. This article highlights the advantages of 70 kV excitation of cadmium, an element of interest for Restriction of Hazardous Substances Directive (RoHS), at parts per million (ppm) levels.

Agilent OneNeb Series 2 nebulizers take robustness and durability to the next level, while retaining the performance enhancements of the original Agilent OneNeb. They can replace conventional glass concentric nebulizers and some inert nebulizers. These nebulizers use Flow Blurring nebulization, which ensures better sensitivity and precision—plus greater tolerance to samples with high levels of Total Dissolved Solids (TDS)—compared to conventional glass concentric nebulizers.

In the past, quantitative analysis with X-ray diffractometry was performed using calibration curves, but due to the progress of computers and analysis software, quantitative analysis using the WPPF (Whole Powder Pattern Fitting) method has now come into wide use. This application report shows that with a benchtop X-ray diffractometer equipped with a high-speed one-dimensional detector, it is possible to obtain an X-ray diffraction pattern suitable for quantitative analysis in about 10-min.
