Sample changer for x-ray devices

Abstract

A sample changer for an X-ray analysis device comprises a tray rotatable around a rotation axis Y and having a plurality of sample positions in a circular pattern, the tray being driven by a motor. The sample changer comprises a telescopic arm having a drive system designed to perform a linear translatory back and forth movement in a Z-direction perpendicular to the rotation axis Y with a gripper arranged on the telescopic arm designed to pick a sample from the tray and to carry the sample to a measurement chamber in the X-ray device and back. The telescopic arm is arranged in an XZ plane perpendicular to the rotation axis Y and is radially directed from the center to an outer circumference of the tray. This mechanism allows pre-selecting and positioning the samples next to a loading opening in order to facilitate a less time-consuming measurement.
