They needed a stronger crystal, but the process of trial and error takes a long time. They decided to enlist help from a robotic system, which can make much smaller, 50-nanoliter samples. Crystals grow faster in small drops anyway. The robotic crystallization process made plenty of crystals, but they did not diffract very well. In 2005, however, the Argonne National Laboratory installed a powerful new x-ray beam, so the researchers took their samples to Chicago. The crystals diffracted the light, but they also fell apart, which limited the amount of data they could get from one crystal.
