Özet: In this study, chemical effect  changes on the lines of  Lα1, Lα2, Lβ1, Lβ2, Lβ3, Lβ4, Lβ6, Lγ1, Lγ2 and Lγ3 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.
