HORIBA EMGA/EMIA Series: Quantitative Elemental Analysis in Nonferrous Metals
Background and Challenges
Nonferrous metals such as aluminum, copper, and titanium are functional, lightweight materials with excellent thermal conductivity and heat resistance, used in a variety of applications. Oxygen, hydrogen, and sulfur are intentionally added to these materials to improve their functions. The concentration of oxygen, hydrogen, and carbon as foreign substances is controlled to improve quality.
Lower oxygen content in pure copper leads to better electrical conductivity, making it important to control oxygen content at ppm levels. Titanium and aluminum require precise control of hydrogen concentration to prevent embrittlement. Carbon and sulfur must be removed as much as possible during refining. For quality control, quantitative analysis of extremely small amounts of these trace elements is essential.
Solution from HORIBA
HORIBA offers advanced solutions for elemental analysis with its EMGA Series (Oxygen/Nitrogen/Hydrogen Analyzer) and EMIA Series (Carbon/Sulfur Analyzer).
"For trace analysis, the higher the number of measurements, the greater the reliability of the results; the fast measurement speed in EMIA and EMGA ensure result reliability and reduce the overall time of a high-volume quality control processes."
