Gas Usage and Filling Services in NMR Systems

Nuclear Magnetic Resonance (NMR) systems are highly sensitive devices that provide molecular-level analysis capabilities in fields such as chemistry, biotechnology, pharmaceuticals, and materials science. To ensure stable and efficient operation, these systems use superconducting magnets that must be maintained at ultra-low temperatures. For this purpose, liquid helium is used, and in some systems, liquid nitrogen is also employed.

Gas filling in NMR devices consists of three main stages: Before filling, the device’s operating status is evaluated and cryogenic system checks are performed. During the filling process, gas, temperature, and pressure values are carefully monitored while the gas is transferred into the system’s cryogenic tanks by expert technical personnel. After filling, connection inspections, leak tests, and system reactivation are carried out.

TGL – Trust Gas Line adheres to the highest standards of purity, technical accuracy, and operational safety in liquid helium and liquid nitrogen filling services for NMR systems. All operations are conducted by authorized and specially trained professional teams.

Moreover, safety and maintenance protocols applied during and after the filling process extend the equipment’s lifespan and ensure the sustainability of system performance. TGL meticulously implements critical steps such as equipment inspection before each filling, connection security, use of personal protective equipment, and environmental safety. When needed, technical consultancy and preventive maintenance support are also provided.

At TGL, we provide uninterrupted gas supply and expert support to all our partners—from universities to private research laboratories—safeguarding device safety, user health, and scientific continuity together.
