2.5 Summary
FAAS and FAES dominated the market for decades but are slowly being replaced by ICP systems. Today, FAAS and FAES systems are limited to situations where only a few elements are analyzed occasionally. “Mass production” analyses in FAAS-FAES are most economical with automatic samplers but even then these techniques are being replaced by ICP-AES and ICP-MS, because of superior detection limits and other factors. These advanced techniques are the subject of the next two chapters.
