Chapter 6. X-Ray analysis of single crystals

Abstract

Data CollectionRadiation Sources A clear introduction to synchrotron radiation and its uses3' from generation of radiation, through descriptions of different insertion devices and characteristics of their radiation, right through to data collection methods has been published.The octapeptide octreotide was crystallized and data were collected on a variety of instr~ments;~' different types of area detectors (TV-type, multiwire proportional chamber and image plate) as well as a four-circle diffractometer were used. Different X-ray sources were also used in the study, ranging from the Hamburg synchrotron DeSy through rotating anode sources to sealed tubes. Octreotide is a particularly useful
