Main application areas

·Analysis, Testing, and Scientific Research:

·Gas chromatography carrier gas: Ultra pure helium gas is the preferred carrier gas, which ensures the accuracy and stability of analysis results due to its inertness, high diffusion rate, and excellent thermal conductivity.

·Nuclear magnetic resonance: Ultra pure helium provides continuous liquid helium cooling for superconducting magnets, maintaining their superconducting state close to absolute zero. It is the core of MRI instruments and scientific NMR research.

·Basic physics research: Ultra pure helium gas is used for creating ultra-low temperature environments in cutting-edge scientific fields such as low-temperature physics and quantum computing.

·Electronics and Semiconductor Industry:

·Protective gas: Ultra pure helium gas provides a pure oxygen free environment in semiconductor crystal growth, fiber drawing, and special alloy welding to prevent material oxidation.

·Leak detection: Ultra pure helium gas utilizes the small size and strong penetration of helium molecules as a tracer gas for high-precision leak detection.

·Plasma process: Ultra pure helium gas is used for etching and cleaning processes.

·High end manufacturing and engineering:

·Welding protection: Ultra pure helium gas provides excellent protection during TIG/MIG welding of reactive metals such as stainless steel, aluminum, magnesium, etc., resulting in high-quality welds.

·Boosting and transportation: Ultra pure helium gas is used in the aerospace industry for boosting fuel tanks and transporting propellants.

·Medical and deep-sea diving:

·Medical imaging: Helium is used as the cooling medium for MRI superconducting magnets.

·Breathing mixture: Helium and oxygen are mixed to create a "helium oxygen mixture" for deep-sea diving, which can prevent "nitrogen anesthesia" and reduce respiratory resistance.

·Other featured applications:

·Balloons and airships: Helium is a much safer buoyancy gas than hydrogen due to its much lower density than air and non flammability.

Safety Warning and Operating Instructions

⚠️  Attention! Helium itself is non-toxic and non flammable, but it poses a risk of suffocation!

·Simple suffocation: High concentrations of helium gas can reduce the oxygen content in the environment, leading to hypoxia and suffocation.

·High pressure risk: Compressed gas stored under pressure may cause the steel cylinder to burst due to physical impact.

·Low temperature risk: The temperature of liquid helium is extremely low (-269 ° C), and contact can cause severe frostbite.

The operation must comply with the following regulations:

1. Storage and use: Store in a cool, well ventilated place. Ensure good ventilation in the usage area and avoid releasing large amounts of helium gas in enclosed spaces.

2. Operation: Use a suitable pressure regulator to avoid opening the valve at high speed. The system must detect leaks. It is strictly prohibited to directly inhale helium gas in order to change the tone, as this behavior can lead to hypoxia, coma, and even death.

3. Leakage treatment: If a large amount of leakage occurs, personnel need to be evacuated and ventilation needs to be strengthened. Wear safety protective equipment when dealing with high-pressure leaks.

4. Personal protection: When operating liquid helium, it is necessary to wear anti freezing gloves, face shields, and safety shoes.
