YSI Hydrodata Appointed UK Distributor for Submersible Spectrometers in Natural Waters
YSI Hydrodata, based in Letchworth Hertfordshire, market a comprehensive range of instruments for monitoring water quality either on-line, in the field or in the laboratory, and the company's parent (YSI) is the world's leading manufacturer of instruments for monitoring the quality of natural water in rivers, streams, lakes, reservoirs, underground and coastal applications. It is logical therefore, for YSI Hydrodata to be chosen to introduce a new range of scanning submersible spectrometers to the UK market.
· The company S::CAN (Austria) has developed innovative compact spectrometers that can measure water quality in-situ
· YSI Hydrodata specialise in natural water quality instruments and are therefore the logical UK partner
· Reagent-free measurement of Nitrate will be a major benefit
Developed by S::CAN in Austria, these instruments represent a genuine step forward in the field of water quality monitoring. For example, the ability to measure Nitrate without the need for reagents will be of particular interest.
Nitrate is a significant pollutant in many natural waters as a result of agricultural fertilisers that contain very high levels. Nitrates are highly soluble, and as a result rainfall and leaching can quickly result in unacceptable concentrations appearing in rivers and underground water resources. This is of great concern to water companies and environmental protection authorities because strict nitrate limits have been created to protect against the health effects of nitrates in water.
In the past, Nitrates have been measured using a variety of techniques, each of which has its limitations; Nitrate ion-selective electrodes have a narrow measurement range and are too sensitive for many applications, requiring frequent recalibration; titrimetric analysers consume reagents, have significant power requirements and are expensive to purchase and operate; and optical sensors are often subject to interferences.
The new submersible UV/Vis spectrometers offer significant advantages over existing methods because, as scanning spectrometers they are able to remove interference from any materials that do not absorb in the precise UV wavelength for Nitrate. Turbidity and temperature are also measured by the spectrometer, and the effects of solids are removed from the nitrate measurement.
The wide range of measurement, from µg/l to mg/l means that these new spectrometers can be calibrated for a variety of applications from ultra pure water to waste water.
Darren Hanson, who will be responsible for sales in the UK, believes that "these new instruments will be extremely popular with the existing YSI customer base, because they simplify the procedure, and reduce the cost of Nitrate measurement with a device that is accurate portable and easy to use"
