Abstract
The invention relates to a sample tray to be used by an automatic sampler having a sample arm. According to an aspect, the sample tray includes wells that can be accessed by a sample arm along a common arc of rotation, without moving the sample arm in and out. According to another aspect, the sample tray has several concentric rows of wells for holding sample pans and reference pans. Each row of wells lies along an inner circumference of the sample tray. The rows are placed so that when the sample tray is rotated, every well can be located on a common arc of rotation relative to a sample arm. According to another aspect, a well in a sample tray is configured with a pan receiving area and finger receiving areas. Gripper fingers can be extended into the finger receiving areas to access pans of different sizes.
