Determination of Trace Elements in Copper by Radially Viewed ICP

Copper is considered to be the first metal used by man and has been mined for more than 10,000 years. Since copper is a soft, malleable metal, early civilizations learned to fashion tools, containers, ornaments and weapons from it. Once it was discovered that the addition of a small amount of tin to molten copper produced an alloy that was harder than copper, the Bronze Age had begun.

Analysis of Stainless Steel by Dual View ICP

Stainless steels are a corrosion resistant family of iron alloys that have a minimum of 10.5% Chromium. Their corrosion resistance is largely due to the formation of a passive chromium (III) oxide (Cr2O3) layer, approximately 1 to 5 nanometers (nm) thick, on the surface of the steel. If this layer is damaged by cutting, scratching or abrasion, it will regenerate, provided sufficient oxygen is available.
