WebAug 15, 2024. X-ray Crystallography. Electrochemistry. The construction of a simple powder diffractometer was first described by Hull in 1917 1 which was shortly after the discovery of X-rays by Wilhelm Conrad Röntgen in 1895 2. Diffractometer measures the angles at which X-rays get reflected and thus get the structural information they contains. WebDec 7, 2024 · Ketamine is absorbed easier when it's finely powdered. Powder ket is just krushed or kooked krystal - if it's not kut, ketamine is ketamine.
