Robust, hand-held EDXRF analyzer for the measurement of heavy metals in soil
Oxford Instruments has launched the new X-MET3000TXS - a fast, lightweight X-ray tube based soil analyzer, designed specifically for measuring heavy metals in soil - offering accurate and reliable identification of pollutant metals and fast analysis of their concentrations.
There is a growing focus throughout the world on cleaning up the environment for health and safety reasons. Legislation now imposes severe restrictions on land quality, especially where plots near cities are converted into cultivated land. Pollution problems, ignored for years, are now coming to the surface, and in many countries the importance of heavy element analysis of soil is increasing.
The X-MET3000TX quickly identifies these polluting heavy metals on-site and defines the limits of "hotspots" to speed up soil removal and remediation work. It can be used for both pre-screening of polluting elements and hot spots, for follow-up during clean up - and if required , for higher level analysis in laboratory.
All the required heavy elements in soil are detected simultaneously - such as Pb, As, Cr, Cu, Zn, Ni, Cd, Co, Se, Mo, Hg, Sb, Ag and Ba with low detection limits. Typically, one measurement takes 15-120 seconds depending on the elements of interest and accuracy required. Results are immediately available, ensuring valuable time is spent on analysis, not waiting for lab results. Measurement data is easily transferred to a PC wirelessly for further inspection and report generation. X-MET3000TXS is compliant with US EPA Method 6200, which is standard method for field portable XRF analysis.
