Chemical industry is a relevant matter in everyday life. The most part of products comes from chemical or petrochemical production processes.

The elementary chemical composition of many compounds may be determined both by traditional X-ray fluorescence (XRF) and by total reflection (TXRF), where it is necessary to verify the presence of micro-traces of pollutants in pure products.

Determination of metal catalysts presence may be made through X-ray fluorescence (XRF), X-ray diffratometry (XRD) and can be effected in order to determine the important chemical-physical properties of materials.

It is important to determine the presence of metals during the production of fuels or lubricating oils. This may be made through X-ray fluorescence techniques (XRF) or through optical emission spectrometers (ROTROIL).

Few ppm sulphur content in fuels is determinated through X-ray fluorescence (XRF). In chemical and petrochemical plant-engineering field the quality check of materials employed to build the facilities is extremely important. The elementary analysis or PMI of metal materials such as valves, pipes, reactors, is made through optical emission spectrometry (OES) and portable X-ray fluorescence (XRF)
