Automatic Specimen Changer for X Ray Diffractometers

It is often desirable in connection with automated X-ray data-acquisition systems to have an automatic specimen changer. A turret-type specimen changer is described here which facilitates examination of more than one specimen in one continuous run.

The specimen changer consists of a turret with a number of radial arms 10, e.g., typically six, each having a spring-loaded specimen holder 12, as shown in Fig. 1. An axially mounted stepping motor 14 accomplishes the actual changing of specimens by rotating the turret through a prescribed angle, which here is 60 degrees. The stepping motor is activated on command from the main control system. As illustrated in the flow diagram shown in Fig. 2, the actual number of specimens can be preselected. The system stops after the preselected number of specimens has been examined.
