一、前言分子发射腔分析(MECA)是英国伯明翰大学R.Belcher等人,于1973年首先提出来的一种新型火焰分析技术。分子发射腔分析是将试样引入到一个发射腔内,腔置于低温火焰(通常是氢—氮焰)中,靠火焰加热蒸发试样,并激发发射分子光谱。
I. Introduction Molecular emission chamber analysis (MECA) is a novel flame analysis technique first proposed by R. Belcher et al. At Birmingham University in England in 1973. Molecular emission chamber analysis is the introduction of the sample into a firing chamber placed in a cryogenic flame (usually a hydrogen-nitrogen flame) that is heated by a flame to evaporate the sample and excite the emission molecular spectrum.
