Abstract
A sample transport device for use in analyzing samples by the headspace analysis technique. The device has a cylindrical platen with counterbored chambers for accepting sample vials. The platen is heated and caused to rotate from a first vial transport point to a sampling point and then back for ejection of the sample vial. Vertical movement of the sample vials is accomplished by use of elevator rods connected to level winding screws mounted below the cylindrical platen.
