Introduction to Energy Dispersive X-Ray Spectroscopy (EDX/EDS) Video by Dr Ben Britton, Imperial College London. For the associated slides - please visit www.expmicromech.com/techniques
Thank you for your video. I would like to ask, is the optical path construction of EDXRF similar to that of EDS? What should be paid attention to when constructing the optical path of EDXRF? What are the measurement standards? For example, the angle between the detector and the X-ray tube, and the distance between the detector, the X-ray tube and the sample.
Nice video Ben. Could I ask about a K shell (1s2 say) electron being promoted to a higher energy L shell (2s2 say). How could that happen as the 2S2 level will be completely filled. Is it more correct to say the K shell electron will leave the atom and an electron from the L shell will take its place. Then an electron from an M shell will fill the vacancy left by the L shell electron i.e. there is a cascade? Thanks
Err - not sure that we would label which transition occurs this specifically in EDX - these effects are seen when we model the probability of each transition, which guides peak heights
Quantitative = putting numbers and precision, e.g. 20 at% Si +/- 1%. Qualitative = describing where the silicon is located, e.g. this is a silicon rich particle.
Thank you doctor.Great.please make a video about how we can determine and guess phases with xrd result and eds result without using xpert highscore lonely.?
