Abstract
A non-seizing taper used for purged capillary tubing connections in gas chromatography that stops capillary tubing at a predictable position within the taper during installation and maintains space for gas to flow past the capillary tubing. The disclosed taper is an improved component of commonly used purged devices such as inlet liners and purged unions. The arresting aspect of the taper simplifies the process of capillary tubing installation while ensuring that the tubing will reproducibly be positioned in the taper. One or more features of the taper prevent tubing from seizing within the taper so that the devices can be reused and ensure that there is open space for a portion of gas to flow around and past the tubing. The angle of the taper, the dimensions of the taper, and the nature of the features within the taper can be adjusted to meet specific performance, usability and/or manufacturability requirements.
