Nickel is commonly used in metal alloys like stainless steel, cupronickel and monel, and nickel plating is a common way to create corrosion resistant metal surfaces. It is also used as electrode material in many types of rechargeable batteries like nickel-cadmium, nickel-metal hydride, and lithium-ion (e.g. LCA, NMC and LNO), with the latter having experienced a high increase in usage in recent years due to the growth of the electric vehicles market.
ICP-OES provides a convenient way to simultaneously analyze nickel metal for multiple contaminants to verify that it is suitable for a given application.
This application note reveals the limits of detection in high-purity nickel using axial plasma observation.
