We can offer chemical analysis of almost all sample types, using various techniques depending on the sample, and the analytes that are required.
X-Ray Fluorescence (XRF) offers a simple methodology for determining the elemental constituents within a material. This testing technique determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source. Either the energy or wavelengths corresponds to a specific element within the sample and allows it to be identified. Based on the total counts of the characteristic energy or wavelength, the quantification of the element can also be determined, showing that XRF can be both a qualitative and quantitative measurement technique.
ICP-OES is a trace-level, elemental analysis technique that uses the emission spectra of a sample to identify, and quantify the elements present. ICP can do a semi-quant scan, is performed to identify and measure a range of chemical elements necessary for the analysis of metal samples, that will look at ~70 elements.
Thermogravimetric Analysis (LOI)
Thermogravimetric Analysis is used to determine the Loss on Ignition (LOI) of samples. Samples are fed into a furnace and the loss in mass at different temperatures is measured. This information is a key requirement to accurate chemical analysis for many samples.
Carbon, Sulfur, Nitrogen and Oxygen can be done via combustion. Combustion is a technique where the sample is heated to high temperatures, and IR cells analyse the gases that are released when the sample is volatilised.
