Single crystal X-ray structure analysis is an indispensable analytical method to obtain three-dimensional structure of materials. Especially to determine the absolute structure of a novel compound, single crystal analysis is virtually the sole method to achieve the goal without any preliminary information. There is no opposition to the potency of single crystal structure analysis, but the use of the method was limited only to crystallographers in the past. However recently, due to the development of equipment and software, it is becoming an analytical technique that everyone can use. In this article, key components of single crystal analysis systems, detectors, X-ray source and software, will be introduced.
