I. Working Principles According to the molecular structure theory, outer electrons of atoms always move via a trapped orbit, which they usually move out of and transit to the orbit of the excited level, if they receive the heat energy provided by a flame. At the same time, attracted by the nucleus and recovering from the excited level to the normal level, the electrons release energy which can be illustrated by the spectra that release specific wavelengths. This method, which measures the luminescence levels of the elements to be determined at specific wavelengths through qualitative and quantitative analyses, is called analysis of spectra based on flame emission, and the instrument which applies to this method is called a flame photometer. Theoretically, the contents of the elements to be determined are proportional to the intensity of the spectra released; however, the flame photometer normally applies only to the quantitative analysis of some alkali metals and alkaline earth metals at a certain concentration range, as limited by the excitement energy.

1.1 Introduction The flame photometer is an analytical instrument based on the principle that the emission spectrum decides the element. When NaCl, for example, is burned, the flame shows the color of yellow. The reason is that the outer electrons, of the Na atom is generated to a higher level by the flame energy, and when it returns to the normal level, it emits the light spectrum with the specific wavelength---yellow light spectrum with a main wave of 5893A°. The flame photometer is an instrument to measure the intensity of this light spectrum to determine the concentration of the measured element. The flame photometer has the advantage of fast analysis and high sensitivity with little sample consumption. For these reasons, it has been extensively employed in such fields as clinical examination, fertilizer and soil analysis, as well as chemical industry. Theoretically, the intensity of the emitted light spectrum is directly reportional to the concentration of the element. The generated energy, however, will affect the result, so this principle is applicable only when the intensity is low. FP-640’s range: when used in clinical examination is: K 0.02mmol/L-0.08mmol/L, Na 1.20mmol/L-1.80mmol/L; when used in other circumstances, the range can be expanded to meet the need reasonability.

1、原理简述: 从分子结构理论了解到:原子的外层电子总沿着固定的轨道运行,当受到火焰提供的热能后,其电子就要脱离原先轨道跃迁到受激能级轨道,由于同时又受到原子核的吸引,电子又从受激能级回复到正常状态时,电子就要释放能量.这种能量是以发射出其元素特定波长的光谱来表示.利用测量元素特定光谱的波长的发光强弱来进行元素定性定量的方法就称之为火焰发射光谱分析法,利用火焰光谱分析法制造的分析仪器就叫火焰光度计. 对火焰光度计来讲,虽然理论上被测元素含量与其发射光谱强度成正比,但由于受到激发能量限制,一般只适用于一定浓度范围的碱金属,碱土金属的定量分析.
