New Application Note for the Determination of Mercury in Waters
Teledyne Leeman Labs (USA) have released a new application note on the determination of mercury in waters by US EPA Method 245.1 VAA spectroscopy. Mercury is a toxic element found throughout the environment. Its mobile nature allows it to diffuse through the air, soils and ultimately into water systems. Fish have the ability to bio-accumulate mercury (in its methylated form) at much higher concentrations than the waters they inhabit. People and wildlife that consume fish high in mercury are at risk. Today, there are over 2,000 water bodies in the United States where advisories are posted to limit consumption of fish known to contain significant levels of mercury. The Clean Water Act (CWA) requires monitoring mercury concentrations in effluent, waste and ambient waters to ensure that our waters remain safe to both mankind and wildlife. Many laboratories employ U.S. EPA Method 245.1 to monitor mercury in effluent, waste and ambient waters. This report provides details for the operation of the new Hydra IIAA according to EPA Method 245.1.

New High-Temperature Laboratory Viscometer
Viscosity specialist Hydramotion Ltd (UK) is pleased to announce an important extension to its ReactaVisc RV3 range of research-grade viscometers des igned primarily for use in laboratory- or pilot- scale reaction vessels.
The new ReactaVisc RV3-HT1 can be used at temperatures up to 250 °C without requiring any special cooling. Efficient design ensures that sensitive components in the head enclosure are protected from overheating, even though the sensor probe itself is at full fluid temperature.
The advantage is that there is no risk of measurement errors resulting from the viscosity changes that would be caused by localised cooling of the fluid around the sensor.
Although robust, the ReactaVisc is light enough to be fitted to a laboratory-sized reaction vessel without requiring additional support. The compact enclosure takes up minimal space at the top of the vessel, leaving plenty of room for ancillary equipment, e.g. for stirring, reagent addition or temperature mea - surement. The sensor is a solid probe with no moving parts, bearings or seals that could wear out or fail in service, so routine maintenance is not required.
Viscosity is measured every two seconds and displayed on the separate VP550 signal processor unit. Output includes a 4 - 20 mA analogue viscosity signal and an RS485 serial data link. The optional ViscoLink software package enables measurement data to be logged and transferred to a PC for analysis.
The ReactaVisc is supplied with a fitting consisting of a compression nut plus an adaptor made to suit the desired installation. The shaft is passed through the adaptor and the compression nut is hand-tightened at the required position, forming an effective seal. The immersion depth is adjusted simply by loosening the fitting, moving as required, and re-tightening.
The whole operation can be completed in seconds. This versatile feature enables the immersion depth of the sensor can be adjusted at will, making it easy to use the viscometer in differing volumes of fluid or in vessels of varying capacity.
No recalibration is needed when the viscometer is transferred from one vessel to another, since calibration is unaffected by the volume of fluid or the dimensions of the container.
The ReactaVisc viscometer is ideal for monitoring changes in viscosity during the course of a reaction, for example in polymer synthesis. As such, it can be used either as a research tool or applied to a small- scale production facility.
Shipped ready for immediate use, the ReactaVisc can be in place and working within minutes of being unpacked.
