Currently, I am using AAS and ICP for metal analysis. Sometime back, I worked on MP-AES, which is a new technique for metal analysis. I got the same results which I got from AAS and ICP. No doubt, ICP is better than both the instruments. But there is very few information about this technique and its reliability.
If anyone is using MP-AES, please suggest which one is better, AAS or MP-AES.
