Testing Methods
Quality control uses special tests to find impurities. Labs use different tools to check purity and spot bad elements. ICP-MS finds tiny metals at very low levels. ICP-OES works for most elements but is not as sensitive. ETA is good for some elements but is slow. FAA is like ICP-OES but does not work for all heavy metals.
Method | Detection Limits | Suitability for High-Throughput | Notes |
|---|---|---|---|
ICP-MS | Sub-parts-per-trillion | Yes | Excellent for trace analysis, especially for manganese |
ICP-OES | Very good | Yes | Good for most elements, but not as sensitive as ICP-MS |
ETA | Good | No | Better for specific elements but not high-throughput |
FAA | Comparable to ICP-OES | No | Limited for certain heavy metals compared to ICP methods |
Strict rules mean companies test often. These tests help remove heavy metals and keep products pure. Every batch must pass these tests to meet the rules.
