The Environmental laboratory undertakes analysis of soil, sediment, rock, water and plant materials for environmental, ecological, geological and agricultural investigations. The laboratory is equipped with a range of sophisticated modern equipment, such as atomic absorption spectrometry, ion chromatography, elemental combustion analysis, UV-visible spectrometry, titrimetry, pH, Redox, electrical conductivity measurements, and X-ray fluorescence spectrometry.
EA Euro 3000
XRF is ideal for rapid and accurate whole bulk elemental analysis in rock or soil samples. The gas-flow proportional counting detector and scintillation detector, or a combination of the two, are used to cover the elements fluorine to uranium. Major elements are analysed on a fused glass bead and trace elements are analysed on a powder briquette. A wide range of international (NIST®) and national (SARM®) standards is used in the calibration procedures and quality control (precision and accuracy) for both major and trace element analyses. Detection limits for the elements quoted, depending on the matrix (combination of elements present), are typically 0.5 ppm.Loss on Ignition (LOI) is a test used in XRF major element analysis which consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape or oxygen is added, until its mass ceases to change. The L.O.I. is made of contributions from the volatile compounds H2O+, OH-, CO2, F, Cl, S; in parts also K, Na (if heated for too long); or alternatively added compounds O2 (oxidation, e.g. FeO to Fe2O3), later CO2 (CaO to CaCO3).
