Abstract:

Laser-induced breakdown spectroscopy (LIBS) technique is widely used to analyze the composition and the concentration of elements in materials,which is based on the atomic excitation and emission spectrum. It has many advantages, such as rapid, multielement simultaneous detection and without sample pretreatment. In this paper, research progress on the application of metal element detection in such fields as alloy, soil, water, and food is reviewed. It is considered that there are some problems in this technology at present, such as low detection accuracy, poor repeatability, unstable detection signal. It is also found that the research and development of LIBS based metal element detection instrument should be developed towards the direction of conventional, portable and high precision.

Key words: laser-induced breakdown spectroscopy, metal element, soil, alloy, food
