We have finished the the version of glow discharge – OES and successfully detect Copper at 0.5%. Although our target for Copper concentration is 0.0001%, this result is still the big step for our long journey. Now we can think about higher resolution and other kinds of heavy metal for detection thank for this results.
… and now we have many ideas from this very first version…and start to collaborate with ANP group for the new project in 2024.
