Trace oxygen analysis in copper

To quickly and accurately quantify the oxygen contained as trace impurities in copper.

Customer needs

A highly pure copper material containing no oxide, such as oxygen free copper (OFC) or tough pitch copper (TPC), which is 99.95% or higher, is suitable for high-end acoustic equipment, signal cable, etc.  Oxygen in copper affects parts performance and quality. Hence, accurate management of lower oxygen concentration is essential. Is there a way to quickly and accurately quantify oxygen in ppm order?
