Sampling issues in polysilicon. Can existing instruments analyze many high-purity substances?

Of course, you can use ICP-Mass to analyze to ppt level.

My company has an ICP, which is used to analyze metals, but there seem to be relatively few in China.

Yes, of course. We use mass spectrometry. Please tell me what exactly you are testing so that you can choose the instrument accordingly.

Can you analyze whether the ppt level is thousands or billions? I always feel that the analyzed data is not authoritative.
