Specific detection limits for GO_XRF76 Nickel Nickel is used in stainless steels, metal alloys, plating, electric batteries and chemicals. It is found in either sulphide or laterite type ores so analytical methods are needed to ensure complete digestion. Refer to the Exploration Grade Analysis section in this guide for descriptions of the GE_ICP21B20, GE_ICP40Q12, GE_ICP90A50 digestion techniques. For description of the GO_ICP21B100, GO_ICP42Q100 and GO_ICP90Q100 techniques, please see the Ore- Grade Analysis section.
