How to characterize high purity material ?
(OP)
Hi all,
I would like to know, what type of method can be used to determine the characteristics of high purity material.
I want to determine the chemical ingredients of high purity aluminum.
Aluminum content is as high as 99.999.

For most elements you will be looking at 20ppm and less, for some you will need to be able to detect amounts of 10ppb. It will take four or five different analysis methods.

They have sent us a ICP OES analysis of the material. But we have to justify the results in more certain way. I don't trust ICP OES method at this level of purity.

What is MTR ?

I would second ICP-MS. Mass spec is an absolute technique since you are counting atoms.
