High purity Inorganic Compounds (Primepure®) was born from our original production and purification
technology, and high sensitive analysis technology which cultivated for a long time.The quantity ofeach element is at the ppb level at most, which offers the most superior product in purity on the market.
◆Highest purity※Metal Base

Purity (by-difference method ) : 99.99～99.9995% ※◆JIS GR + More then 30 metallic impurities guaranteed under ppb level. (except a few parts)
