In this study,
chemical effect  changes on the lines
of  L_α1, L_α2, L_β1, L_β2, L_β3, L_β4, L_β6, L_γ1, L_γ2 and L_γ3 were examined by using a Rigaku single-crystal
(LiF) ZSX 100e wavelength dispersive X-Ray spectrometer (WDXRF). In our
research, proportional counter (PC) was used for wavelengths less than 0,336 nm
and scintillation counter (SC) was used for wavelengths more than 0,154 nm.
X-rays could be counted simultaneously both PC and SC in LiF crystal of our
device. Depending on the chemical state of the mater, chemical effect may bring
about some modifications in values of energy of X-Ray line, full width at half
maximum (FWHM), asymmetry index (AI). These effects are different for each main
group elements have been investigated to what or what could be caused these
differences. Also chemical effects researched depend on status of the chemical
bonds and number of valence electrons. Results of the measurements evaluated by
Orjin 8.0 program and in order to prevent from faults may occur during the
measurements, best experimental geometry conditions determined.
