| Electrical Spark-Optical Emission Spectroscopy (OES) has been used for over 50 years for the direct analysis of alloys in the aluminum industry. This method has undergone continual improvement over time, but conventional OES can barely reach the new specification limits required for some critical aluminium alloys. As part of a continuous improvement process, instrument manufacturers, academic and industrial researchers, are now showing a particular interest for Laser Induced Plasma Spectroscopy (LIPS), also know as LIBS for Laser Induced Breakdown Spectroscopy, as an alternate and/or complementary approach for the analysis of aluminum alloys.;In our work, we have optimized the ablation conditions with a commercially available laser induced plasma spectrometer and we have obtained better precision than optical emission spectroscopy. We have demonstrated that the ablation phenomenon by the laser source is less dependant to the chemical composition of the alloys than the electrical source. We also demonstrated the application potential for mid and long term of laser induced plasma spectroscopy for direct analysis of aluminum alloys. We have developed a systematic method for detection of matrix effects in emission spectroscopy. |
