This work was aimed to improve the instrumental detection limit and sensitivity of 17Cl, 37Rb, and 38Sr elements present in solid samples by using the advanced polychromatic wavelength dispersive X‐ray fluorescence spectrometry method. Instrumental measuring parameters, as well as study of calibration curves of K and L shell spectral lines, were evaluated to select the best conditions for 17Cl, 37Rb, and 38Sr quantification. From the results, it was observed that the detection limits of the Rb Kα and Sr Kα spectral lines were lower than those of the Kβ1,3 and Lα spectral lines. From the calibration curves, it was concluded that Kα spectral lines are more suitable than Kβ1,3 and Lα lines to identify the traces of 17Cl, 37Rb, and 38Sr elements in different types of solid samples.
