What can be used to detect impurities at those level? Maybe there is an additional machine needed that can also be built in a garage.

The industry standard is HPLC (high performance liquid chromatography). Those things go for tens of thousands of dollars up front, plus maintenance and consumables.

If there was a less costly way of doing it, you bet companies would have settled on that by now.
