Laser Induced Breakdown

There is a great number of packaging materials, such as bottles and boxes, are made of plastics (polymers). Additives such as plasticizers, antioxidants, antistatic agents, and lubricants may be used for the production of packaging materials. The worst effect of plastic production is deterioration of the environment. Recycling solves this problem and the initial step is identification and classification of the polymers and determination of different elements present in it. In this research, spectroscopic analyzes were performed using Laser Induced Breakdown Spectroscopy (LIBS) for plastic materials samples of drug containers that collected from manufacturing factories located at Khartoum city, Sudan. The samples were collected before and after used, were irradiated by Nd: YAG laser at 266 nm, repetition rate 2Hz, with pulse energy of 80mJ. The recorded spectra of the samples were analyzed using National Institute Standard and Technology (NIST). and Origin Lab Pro 9 data analysis software. All elements present in plastic drug bottles were detected using laser induced breakdown spectroscopy. The elements that detected are (Ca, Cd , Ra, Ac, W, V, Na, Pm, Cl, K, , Ce, Ar, Nd, Ac, Tc, Sc, Li, Pa, and Pb).

Laser Induced Breakdown

Spectral investigations in the UV-VIS range of selected Al alloys and composites, used in the construction of armament components as well as drones, were performed using LIBS technique. Two Nd:YAG lasers were applied: a short pulse 4 ns 60 mJ laser and a long pulse 200/400 (up to 1000) us (~ 2/4 up to 10 J) laser. In experiments with a short laser pulse only atomic spectra were observed while for long pulses, also molecular transitions have been recorded. Electron temperatures of created plasma were found on the base of Boltzmann law. Temperatures are clearly higher for short pulse excitation. Full Text: PDF ReferencesA. Miziolek, V. Palleschi and I.

Laser Induced Breakdown

Laser-induced breakdown spectroscopy was used for the fast determination of calcium concentration in the internal tissues of a single seed. Compared with conventional methods, LIBS had obvious advantages, such as a little analysis spot, little ablation, high precision, and small influence on the seed vigor.

Laser Induced Breakdown

Laser-induced breakdown spectroscopy has been used to determine carbon content in steel. The plasma was formed by focusing a Nd:YAG laser on the sample surface. With the use of time-resolved spectroscopy and generation of the plasma in nitrogen atmosphere, a precision of 1.6% and a detection limit of 65 ppm have been obtained. These values are similar to those of other accurate conventional techniques. Matrix effects for the studied steels are reduced to a small slope difference between the calibration curves for stainless and nonstainless steels.
