Crystal breakage
WebMar 31, 2024 · Combined normal and shear stress on particles occurs in many devices for solid–liquid separation. Protein crystals are much more fragile compared to conventional crystals because of their high water content. Therefore, unwanted crystal breakage is to be expected in the processing of such materials. WebNov 15, 2024 · For crystal breakage there exists at least two major factors for investigation: the amount of breakage occurring (distributions), and form of the breakage mechanism (modes). Before dealing with the former, it is important to first describe what is meant when referring to different breakage types or “modes”.
