Abstract
A sample manager of a liquid chromatography system uses a sample tray having a base with side walls separated by a cross wall that divides the base into two compartments. The side walls and cross wall bound each compartment on three sides. A fourth side of each compartment is open. Each compartment is sized to closely receive a sample-vial carrier. Each compartment has a magnet affixed to a bottom surface at an edge of the open fourth side. Each of two drawers slides into the open fourth side of one compartment. Each drawer has a support surface with a magnet affixed at an edge of its bottom side, which aligns with the magnet affixed to the bottom surface of the compartment. The magnet of the drawer and the magnet of the compartment bias the drawer into its compartment when the magnets are brought into proximity of each other.
