Abstract

A biological crystal formation screening apparatus uses an x-ray diffraction technique to analyze the sample containers of a sample tray for the presence of crystal formation. An x-ray source is directed toward a sample under investigation, and a two-dimensional x-ray detector is located to receive any diffracted x-ray energy. A positioning apparatus allows the different sample containers of a tray to be sequentially aligned with the source and detector, allowing each to be examined. The sample container is arranged such that a sample is located relative to the well solution so that the x-ray beam is directed to the sample without being incident on the well solution.
