Abstract
A sample cup insert has a tubular wall and a flange extending inwardly at an acute angle from the tubular wall. When the sample cup, into which the sample cup insert is inserted, is filled with sample and sealed by a film that forms a window through which the sample is analyzed, air bubbles collect under the film. The air bubbles are transferred under the flange of the sample cup insert, and out of the portion of the sample to be analyzed, by rotating the sample cup, and allowing the air bubbles to flow up the side of the sample cup insert over the flange, and then returning the sample cup to its original position, thereby trapping the air bubbles under the flange. The flange of the sample cup insert retains these air bubbles outside of the portion of the sample to be analyzed.
