SMART-Chart-GDMSLet's take a deeper dive into our SMART Chart!

Real materials are not pure! They contain various impurities of naturally occurring elements. The type, concentration and spatial distribution of impurities are of particular concern to many advanced technologies. The success of these technologies and industries relies on the high purity feedstock (e.g., 99.995%+) and contamination-free processing and engineering.

As a global leader in the 3rd party materials testing service, Eurofins EAG is launching a series of talks focusing on purity assay and trace analysis. Our talks will discuss trace analysis using both solid sampling techniques and solution-based sampling technique, including Glow Discharge Mass Spectroscopy (GDMS), ICP-OES, ICP-MS, Laser Ablation – ICP-MS, Laser-Induced Breakdown Spectroscopy (LIBS), Instrumental Gas Analysis (IGA), Residual Gas Analysis (RGA), ETV- ICP-OES, etc. The fundamental of each technique and practical industry application will be presented.

The webinar will be focused on full survey chemical analysis using solid sampling high resolution GDMS. The talk will cover the fundamentals of GDMS, and present case studies in practical industrial applications, such as full survey chemical analysis of high purity alumina, long-term process control of critical impurities in nuclear grade graphite, key impurity monitoring of superalloys, and depth specific measurement of engineering coatings.
