Laser-induced emission technology

Other spectrometry technologies include sliding spark (AGR and the University of Duisberg, Germany), identifying a wide range of plastics and additives, and laser-induced emission (LIESA), by Krupp, the University of Kaiserslautern, and BASF Magnetics. 

Laser-induced emission spectroscopy analysis (LIESA) is a similar technology, in which a beam of laser light is directed onto the surface of the specimen. This induces a short-lived hot plasma that comprises free electrons, excited atoms, and ions of very high electric charge. 

At present the real strength of LA lies in the measurement of distribution patterns of minor and trace elements in solid samples with high spatial resolution. Homogeneity testing is an application of LA-ICP-MS. There is an increasing demand for the development and validation of accurate and robust analytical technologies for the determination of the chemical characteristics of polymeric products in support of industrial needs, EC regulations (e.g. Directive on toy safety) or research. Needs are particularly acute for techniques able to determine trace element contents in solids with a minimum sample preparation. For this purpose, laser ablation-based methods, such as LA-ICP-AES/MS and laser-induced plasma atomic emission spectrometry (LIP-AES, LA-AES or LIBS) have already...
