Nuclear magnetic resonance (NMR) spectrometers have a wide range of applications and are important analytical instruments in fields such as chemistry, biology, and materials science. NMR uses liquid nitrogen for the cooling of the superconducting magnet, which is its core component with a coil material that needs to be kept at extremely low temperatures to generate a high-intensity, stable magnetic field.
The role of liquid nitrogen for NMR
Bulk supply considerations
Purchasing bulk liquid nitrogen from external suppliers is the traditional method for supplying liquid nitrogen, but this method suffers from problems such as unstable supply, evaporation losses, storage risks and high long-term costs. The emergence of liquid nitrogen generators has provided a more reliable and economical cryogenic solution for NMR systems.
Liquid nitrogen generators can sustainably produce high-quality liquid nitrogen exactly where it's required. In the long run, their convenience, safety, reliability, and cost-effectiveness offer a better alternative for a reliable liquid nitrogen supply. Liquid nitrogen generators are fast becoming a well-known technology and essential part of laboratories using NMR devices.
On-demand LN2 generation benefits
Liquid nitrogen is crucial for the stable operation of NMR superconducting magnets. Compared to traditional liquid nitrogen supply methods, liquid nitrogen generators offer laboratories a safer, more economical, and sustainable cryogenic solution.
Compared to traditional liquid nitrogen supply methods, Noblegen's industry-leading plug-and-play liquid nitrogen generator offers numerous advantages, including higher reliability, safety, and convenience.
- Ready to use immediately: Multiple flow rates and models are available.
- On-site liquid nitrogen production: eliminates the need for frequent liquid nitrogen transport, reducing storage and transportation costs.
- Reliable liquid nitrogen supply: The liquid nitrogen generator ensures a continuous and uninterrupted supply of liquid nitrogen, eliminating the need to purchase bulk liquid nitrogen.
- Safety: Eliminates the risks associated with large-scale transportation and storage of liquid nitrogen.
- High efficiency and energy saving: Built-in large-capacity dewar flask, automatically enters standby mode after being filled with liquid nitrogen, and eliminates liquid nitrogen evaporation loss through a closed-loop control system.
- Simple maintenance: Requires minimal maintenance, saving significant time and costs.
- Automated production: Built-in intelligent liquid level sensor enables automated production of liquid nitrogen.
- Cost-effectiveness: Reducing reliance on bulk liquid nitrogen suppliers makes liquid nitrogen generators more economical in the long run than purchasing bulk liquid nitrogen.
- Convenient: Continuous supply of liquid nitrogen on demand
- Environmentally friendly: Eliminates carbon emissions during transportation.
