Abstract
Fittings are the “cement” of the LC system, working with the tubing to connect the various modules. The fittings must be inert and leak-free; they also must add no unnecessary volume to the system. Two types of fittings are used in the LC. For pressures below 100 psi, low-pressure plastic fittings are used with Teflon tubing. Compression fittings, generally made of stainless-steel, are used with stainless-steel tubing for pressures up to 6000 psi. Mismatched or improperly-assembled fitting components will result in leaks and/or broadened peaks. A large number of fitting variations is available—some brands are interchangeable; many are not. It is important to be able to readily identify the different fitting types in order to avoid fitting-related problems.
