X-ray fluorescence (XRF) spectrometry is an elemental analysis technique with broad application in science and industry. XRF is based on the principle that individual atoms, when excited by an external energy source, emit X-ray photons of a characteristic energy or wavelength. By counting the number of photons of each energy emitted from a sample, the elements present may be identified and quantitated. Aczet's XRF product is based on a German technology, used to measure the composition and purity of materials and is mainly applied in industrial quality control and in process control for manufacturing processes in industries such as Jewellery, Metals and Mining, Construction materials and Chemicals.
