Iranian Technologists Develop "Laser Induced Breakdown Spectroscopy" for Elemental Analysis

TEHRAN (ANA)- Experts at a technological company in Iran have used locally developed know-how and technology of "Laser Induced Breakdown Spectroscopy" (LIBS) to build products and equipment in the field of laser and plasma.

Iranian Technologists Develop "Laser Induced Breakdown Spectroscopy" for Elemental Analysis

Hajar Zarei, the managing director of the Iranian technological company, said that they have focused their activity in the firm on laser, plasma and electromagnetic waves.

“Our company operates with the aim of indigenizing know-how and up-to-date technology in the field of mining and energy. Currently, using knowledge-based equipment, we have laid the ground for the development of knowledge-based products and the development of research in the field of laser and plasma, optics and other related technologies,” she said, according to a report by the Iranian Vice Presidency for Science and Technology and Knowledge-Based Economy.

Zarei referred to elemental analysis method as one of the capabilities of their technology company, saying, "This method is a form of atomic emission spectroscopy that uses high-power lasers to vaporize materials and produce plasma. Then, the plasma created is then induced by the laser, and the atoms emit light at specific wavelengths that can be used to identify the elements in the sample. Using this technology, which is based on the direct examination of the sample, accurate and practical information can be obtained without the need for preparation or with minimal preparation based on the analysis of the spectral lines emitted from the induced plasma by laser.”

“Given the outstanding characteristics of the laser, the use of elemental analysis device has broadened in various fields in the last decade, particularly in the oil industry; because it is possible to achieve high speed and accuracy in measurement and assessment. Moreover, a broad range of applications have been proposed for this method, from space exploration to cultural heritage and food quality control,” she said.

She further said that material assessement, the ability to detect light elements such as lithium, aluminum, magnesium and carbon, the ability to detect all elements even gold with ppm accuracy despite the interference of gold and iron peaks with each other, high speed and accuracy in measuring and checking materials remotely at nuclear, geological, space exploration and archeology sites, evaluating the relative abundance of each element in the sample by various analytical methods and quick and complete analysis on an atomic scale are some of the capabilities of laser elemental analysis method.
