Application of internal standard method for determination of 3D-transition metallic elements in
flame atomic absorption spectrometry using a multi-wavelength high-resolution spectrometer

Flame Atomic Absorption Spectrometry (FAAS) is a technique, which has been extensively applied for the quantitative
determinationof different elements in inorganicmaterials. Aparticular element canbe quantified only once formeasurement
with the help of a conventional atomic absorption spectrometer; whereas, by using a spectrometer system comprising of a
xenon-lamp, continuum light source and an echelle-type spectrograph, it is possible to conduct sequential multi-element
and multi-wavelength analysis, thus enabling the FAAS measurement over a certain wavelength range simultaneously. Due to
this superior performance, an internal standard method, which can correct the physical interference in the solution sample
as well as a long-time drift of the measurement system, can be properly employed, which leads to an improvement in the
analytical precision of FAAS. In this study, selection criteria of an internal standard element which could be applicable for
the measurement of 3D transition metals, such as Fe, Ni, Ti, were investigated in details, indicating that platinum-group
elements could be suitably selected for the internal standard method. In Ti-Pd, Ni-Rh, and Fe-Ru systems, chosen as typical
combinations, several variances of the analytical results; for instance, a variation in aspirated amounts of sample solution and a
short-period drift of the primary light source, could be corrected and thus reduced, when the absorbance ratio of the analytical
line to the internal standard line was measured.
