Answer:No. The vacuum pump and degassing chamber are separate components.

Question: What should be checked after replacement?

Answer:Solvent-line connections, leakage, successful priming and absence of persistent gas bubbles.

Application Note

The Shimadzu DGU-20AR Vacuum Degassing Chamber is a replacement solvent-path component for compatible Shimadzu online degassing assemblies. During chromatographic solvent delivery, dissolved gas can form bubbles as pressure, temperature or solvent composition changes. The chamber provides the membrane-based degassing interface within the vacuum-assisted solvent management system, allowing gas to transfer away from flowing mobile phase while liquid remains in its designated path. This part is useful when diagnosing a damaged chamber, declining degassing efficiency or leakage isolated to the degasser module. Before replacement, stop the liquid chromatograph, disconnect electrical power where required, release pressure and handle residual mobile phase using suitable precautions. Reconnect the solvent lines without twisting or pinching tubing, then prime and inspect the system for leaks and persistent bubbles. The chamber is not the vacuum pump, intake air filter or the complete DGU degasser. Replacement should match the original degassing assembly and its solvent compatibility requirements.
