    • A flame detector analyzer of the type wherein a sample gas is introduced into a flame formed by burning a fuel gas in presence of a combustion supporting gas, comprises a background providing device for supplying a background component gas capable of emitting a characteristic spectrum having the same wave length as that of the characteristic spectrum of a measuring object component contained in the sample gas, the light spectrums emitted from the measuring object component and the background component gas being received and treated to be detected, thereby increasing the measuring accuracy for the measuring object component and improving the resolving power at a low concentration detection region.
    • 一种火焰检测分析仪,其特征在于,在燃烧支持气体存在下,将样品气体引入燃烧燃烧气体所形成的火焰中的方法,其特征在于,包括:背景提供装置,用于供给能够发射具有该气体的特征光谱的背景成分气体 波长与样品气体中包含的测量对象成分的特征谱的波长相同,从测量对象部件发射的光谱和背景分量气体被接收和处理以被检测,从而增加测量对象的测量精度 并提高低浓度检测区域的分辨能力。
