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?
Raw Copper Material
Oxygen to trace amount ranges in conformity with JIS H 1067.

Result Sample: copper
| time | Sample weight (g) | Oxygen (mass ppm) |
|---|---|---|
1 | 1.019 | 4.7 |
2 | 1.023 | 4.8 |
3 | 1.022 | 5.2 |
4 | 1.016 | 5.1 |
| 5 | 1.012 | 5.1 |
| Average | 5.0 | |
Standard deviation | 0.2 | |
Variation coefficient (%) | 4.4 | |
| Range | 0.5 | |
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.
High-speed analysis.
Easier maintenance.
