Embodiment Construction

[0052] In the following description, similar features in different embodiments have been given similar reference numerals. For the sake of simplicity and clarity, that is, so as not to unnecessarily complicate the drawings with unnecessary reference numerals, not all drawings contain references to all components and features; references to references to some components and features, and components and features of the present disclosure shown in other figures can be easily inferred therefrom.

[0053] refer to Figure 7 , 7AThrough 7C, 8 and 8A through 8D, a mating assembly 200 is shown according to one embodiment. Although the fitting assembly 200 is depicted as a joint type fitting, it should be understood that the features of the improved fitting assembly described herein can be applied to other types of fittings adapted to receive tubing locked in place with a compression nut and ferrule. Component or any component part of an analytical system, such as a cap, valve, bonn...

Abstract

An improved fitting assembly for analytical devices is provided. The fitting assembly includes a tube securable to a fitting component via rear and front ferrules and a nut. The fitting component includes a body having a cavity for receiving the tube and ferrules. The body also includes a channel connecting the cavity to a leak chamber defined in a space between the tube, the fitting component andthe inner sidewall of the nut body, the leak chamber being in fluid communication with the exterior of the nut body via the channel in the nut body. Sealing elements are provided between the tube andnut for encouraging leaks to flow through the leak path. A method for detecting leaks in the fitting assembly is also provided.

Description

technical field [0001] The present invention relates generally to analytical devices, fitting members and fittings, and more particularly to press fit members adapted to receive and connect tubing and means for detecting leaks therein. Background technique [0002] Mating members and fittings are typically used to sealably connect the tube to another device, another tube or simply cap the tube. When used in analytical systems, mating members and fittings are most commonly used to sealingly connect two tubes together so as to allow leak-tight fluid communication between the tubes. The mating member may also be part of the analysis device and the actuation mechanism for receiving different types of tubing. [0003] figure 1 and 1A One common type of mating assembly 10 is shown in (Prior Art). A double ferrule 12 formed by a front ferrule 12a and a rear ferrule 12b grips the tube 14 near its end, forming a protrusion 13 forward of the ferrule 12, which is commonly referred ...
