According to one aspect, the automatic sampler includes a cell having a sample platform and a reference platform; a sample tray; and a sample arm. The sample tray has wells into which sample pans and reference pans are inserted. The geometry of the automatic sampler device permits the sample platform, the reference platform, and the wells in the sample tray to be accessed by the sample arm along a common arc. According to another aspect, the automatic sampler device includes a sample tray with wells, a sample arm, and a gripper device. The gripper device has gripping fingers. The gripping fingers open or close in a manner that tends to center objects grasped by the gripper device. According to another aspect, the automatic sampler device includes a sample tray with wells, a sample arm, and a gripper device. The sample arm has an optical sensor and an electrical sensor. The optical sensor and electrical sensor can be used to detect a pan grasped by the gripper device. According to another aspect, the automatic sampler device includes a sample tray with wells, a sample arm, and a gripper device. The gripper advice is capable of grasping pans of different sizes.
