Understanding what’s X-ray tubes

Small spot collimation for PCB component analysis. Be aware that if your sample is thinner than the penetration depth, elements in a support or anything behind the sample may be visible in the XRF spectrum. The pulses generated by the detector are processed by pulse-shaping amplifiers. High-energy X-ray photons can create the same effect, allowing us to excite a sample with the output of an X-ray tube or any source of photons of the proper energy. WDXRF spectrometers often offer more flexibility for the researcher as well as very good sensitivities. The necessary information and formulas for such calculations are not specific to XRF and can be found in a variety of textbooks and online sources.
