The strong li emission from the flame at this wavelength

Assignment Help Chemistry
Reference no: EM13689952

Problem- Li can be determined by flame atomic absorpion spectrophotometry at 670.8 nm. How is this possible, given the strong Li emission from the flame at this wavelength? What effect does the Li emission have on the noise associated with the Li atomic absorption measurement? Why are the Air Supported flame recommended for Li atomic absorption measurements and the Nitrous Oxide Supported flame recommended for the Li atomic emission measurements?
