Versatile Slot Burner Design for Atomic Absorption Spectrometry

摘要

We have designed a long-path-length burner for spectroscopic methods which depend upon the absorption process, namely, AAS, CFS, and LEI. The burner is capable of producing premixed and diffusion flames which employ a variety of flame gases. Many new premixed and diffusion flames produced on this surface burner have been investigated at atom reservoirs for AAS, CFS, and LEI. The temperature of the premixed flames was increased by adding an auxiliary oxidant at the surface of the burner without increasing the possibility of flashbacks.
