Perhaps no earlier technology has been as interested and anticipated as the nanotechnology, which is the magic key to progress in science and knowledge. The applications of nanotechnology are not limited to one branch of science but extend their applications to all branches and applications. The production of nanoparticles by way of laser ablation of solids in both gas or vacuum and liquids have been widely explored over the past two decades. The method of laser ablation has received considerable attention as a new technique for the production of nanoparticles. Which represent the phenomenon of the interaction of the laser with the material, since the amount of mass removed depends on the Laser parameters (pulse duration, number of pulses, energy, wavelength, properties of the target material, surrounding environment).
The using of laser ablation in combination with ICP-MS for the determination of major, minor and trace elements as well as isotopic ratios in solids and liquids has grown over the past decade. There are several advantages using laser ablation as a sampling technique: Almost no sample preparation and no contamination from solvents and acids, less interference's due to the absence of solvents and acids, spatial resolution to as low as few µm are possible, elemental and isotopic information are obtainable, limits of detection are superior to other solid sampling techniques and the speed of data acquisition allows large quantities of samples to be analyzed within reasonable time. The results obtained have shown that this technique can be used for screening of plastics materials in terms of BFRs and OTCs which are under regulation by most of the countries especially in EU countries. The method has LWR of 30-1000 mg kg-1for Br and 120-1600 mg kg-1for Sn. Besides the LA-ICP-MS method can be used for heavy metals (Cr, Cd, Pb and Hg) analysis in plastics with optimization of some laser parameters and also using LA as an extraction technique some plastic additives can be screened by GC-MS.
