Peg 6000 xrd peak position

WebThis paper derives the physical meanings of peak position, peak width and height of an X-ray diffraction peak from the analyses of the Bragg’s equation, the Scherrer’ s formula and the principle of peak intensity calculation. The geometric characteristics of an asymmetric peak are clarified by means of experiment. The relationships between peak shape and … WebHowever, I haven't seen notable difference in PEG6000 vs PEG8000 during phage precipitation, but most of the studies were done using PEG8000.
