摘要: 本文探讨了石墨管内被测原子间的平衡关系,从理论上推导了基态原子数与吸光度之间的系数β,计算了部分元素的理论特征量N值.

关键词: 平衡, 特征量, 原子化效率

Abstract: The equilibrium among those determined atoms is studied.The coefficient β between numbers of ground-state atoms and the absorbance was derived theoretically, and the characteristic amount for the number of elements was calculated.Comparing with the value presented by Varian Company, it was shown that the atomization efficiency for GTA-95 atomizer was over 80% calculated with peak height for the more volatile elements such as Zn and Cd.20%~50% for those medium volatile elements such as Cu, Ni, Mg, Ag, Cr etc.and 10% below for less volatile elements Al, Ti and Vetc.

Key words: Equilibrium, Characteristic amount, Atomization efficiency
