Connectors & Unions

Connectors & Unions are essential components in chromatography that help to make a chromatographic system efficient and reliable. They are used to securely and tightly connect different parts of the system such as columns, detectors and injectors. These connections are critical for maintaining flow and preventing leaks that could affect the accuracy and reproducibility of analyses.

Connectors are components that join two or more capillaries together. They are available in different shapes and sizes to meet the specific requirements of chromatographic applications. Connectors are often made of materials such as stainless steel, PEEK (polyetheretherketone) or PTFE (polytetrafluoroethylene), which offer high chemical resistance and mechanical stability. There are several types of connectors, including straight connectors, T-connectors and angle connectors. Straight connectors are used to join two pipes in a straight line, while T-connectors and elbow connectors allow for branching and directional changes in the system. These connectors provide flexibility in the design and customisation of the chromatographic system.

Unions are special connectors that allow capillaries to be easily disconnected and reconnected without compromising the integrity of the connection. They are particularly useful in systems that require frequent maintenance or reconfiguration. Unions are also made of materials such as stainless steel, PEEK or PTFE and offer high resistance to chemical influences and mechanical stresses. There are different types of unions, including inline unions and reducing unions. Inline unions connect capillaries with the same diameter, while reducing unions connect capillaries with different diameters. This flexibility makes it possible to effectively integrate different components of the chromatographic system.
