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?
Oxygen to trace amount ranges in conformity with JIS H 1067.
Result Sample: copper
|time||Sample weight (g)||Oxygen (mass ppm)|
Variation coefficient (%)
By using EMGA, it is possible to analyze the low concentration of oxygen in minutes.
Wide concentration measurement range:
0.6ppm〜 5%(m/m) for oxygen and 0.6ppm〜 3%(m/m) for nitrogen for the sample standard concentration less than 10ppm.
