Benefits of technology

Inventions described in this patents have combined certain properties from different alloys into one unit with improved accuracy, stability, ease of operation, and reduced costs compared to existing methods like X ray fluorescence or atomic absorption spectrometry. These technical features improve efficiency and reduce errors during analyzation processes while maintaining high standards of purity and reliance on precise measurements made through these techniques.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at analyzing alloys while reducing costs associated with laborious preparation processes or relying solely upon physical standards. Existing methods have limitations because they require multiple steps and can take longer than necessary. There also exist some existing methodologies only partially addressing specific issues like matrix fitting/interference caused by different types of impurities found within each component being tested.
