Insulin derivative measurement on a laboratory powder diffractometer

After successful structure refinement of lysozymefrom laboratory powder data, we continued experiments with more sensitive sample. Crystals of bromo derivative of insulin have been obtained by the batch crystallization method and loaded into the glass capillary. The capillary has been mounted onto the X'Pert PRO powder diffractometer configured in focusing transmission geometry. The data were collected in series of one hour scans in orther to monitor sample decay. The quality of obtained data was sufficient for crystallographic investigation.
