CEM (Continuous Emission Monitoring) techniques need to be developed for the appropriate control of volatile heavy metals contained in the flue gas from waste incineration. LIBS (Laser Induced Breakdown Spectroscopy) is one of the promising methods for the real-time and in situ measurement of trace elements in gas. All elements existing in laser-induced plasma are excited and radiate lights in their own line spectrum. And they enable the identification and quantification of each element. In order to gain a foothold in the online measurement of cadmium in flue gas by LIBS, the mid-gut gland of scallop that is known as waste product having an extremely higher concentration of cadmium was selected as the combustion sample. The transient change of cadmium emission from mid-gut gland combustion was continuously analyzed by LIBS.
