We use ICP-OES equipment to determine precious metals content in scrap lots to parts-per-million levels so our customers achieve maximum returns on their recycling materials. The ICP-OES is also used to verify that our alloys and raw materials are of the highest purity.
ICP methods are extremely highly precise techniques used to measure combinations of metals to .001% accuracy. Therefore small traces of metals can be detected. All this work is done in house.
