Real-time, In Process Chemical Analysis for Clean Energy Manufacturing

Tomorrow I will present a seminar to Applied Materials employees inSanta Clara California discussing a new ‘Green Chemical Analysis’technology.

Chemical analysis is a part of our everyday lives,from identifying the components of consumer goods to monitoring material manufacturing processes.

Classical chemical analysis of solidmaterials generally requires that a sample be dissolved in an acidsolution. The cost and environmental impact of chemical analyses arehard to predict and include labor, consumables, waste products, and lost productivity. For any off-line analytical measurement process, inferior product may be produced during the measurement time. The availabilityof on-line real-time analysis with associated feedback process controlprovides cost savings across all manufacturing.

On-line metrologyfor elemental analysis involving x-ray and other technologies exists,with advantages and disadvantages of each. A new disruptive technologyfor enabling efficient manufacturing of batteries, solar, andsemiconductor products has been developed and commercialized based on a30 year $50 million investment by the Department of Energy R&D atthe Lawrence Berkeley National Laboratory.

The technology is laser sampling and analysis of elements (periodic chart). This laser based approach has advantages of no sample preparation, noconsumables, no waste products, tiny sample requirements (nanograms orless), in process real-time monitoring, and can detect every element onthe periodic chart. Spatial and depth resolution on the nanometer scale with attogram sensitivity during a single laser pulse are attributes of this technology. At LBNL, we have pioneered this technology throughunderstanding of fundamental principles and development of conditionsfor accurate-precise analysis.

At Applied Spectra, we fabricate instruments for measurements in application markets toinclude clean energy technologies. Our laser technology provides acompetitive advantage for manufactures in eliminating laborious chemical analysis procedures, and minimizing the impact of chemical analysis onthe environment. The presentation will provide an overview of thetechnology, describing the fundamental principles, the advances,available systems and several industrial applications.

I welcome questions in advance of tomorrow’s talk via this blog.
