Introduction
Helium is one of the most essential gases in both industrial and scientific domains. Within this context, the term Helium-1 gas often arises, especially in technical applications that demand precision and advanced performance. But what exactly is Helium-1 gas, and how does it differ from other helium variants? This article dives deep into its definition, uses, and significance in modern technology, while also introducing YIGAS Group, a major global supplier of helium and other industrial gases.
What Is Helium-1 Gas?
Helium-1 (He I) gas typically refers to helium in its normal gaseous state, specifically at temperatures above its lambda point (2.17 K). In scientific discussions, especially within cryogenics, “Helium-1” is used to distinguish it from “Helium-2,” which is superfluid helium below 2.17 K. While both are isotopes of the element helium, they exhibit different physical properties based on temperature and pressure.
In industrial use, Helium-1 is commonly just called helium gas and is valued for its inertness, low boiling point, and non-reactive nature. It’s used in applications from cryogenics to leak detection and aerospace.
Key Properties of Helium-1 Gas
Helium-1 gas exhibits a range of unique characteristics that make it indispensable for various industries:
- Chemical Symbol: He
- Atomic Number: 2
- Boiling Point: -268.93°C (4.2 K)
- Density: 0.1786 g/L at STP
- Odorless, Colorless, and Tasteless
- Inert and Non-Toxic
- Non-Flammable and Extremely Light
How Helium-1 Gas Is Produced
Helium is primarily extracted from natural gas fields that contain high concentrations of helium. The typical steps include:
- Extraction: Sourcing natural gas with helium concentrations of 0.3% or more.
- Purification: Removal of other gases like nitrogen, methane, and carbon dioxide.
- Liquefaction: Cooling the gas to isolate and compress helium into liquid form for storage or transportation.
- Re-Gasification: Helium-1 is delivered in its gaseous form for end-use applications.
Main Applications of Helium-1 Gas
1. Cryogenics
- Helium-1 is the only gas cold enough to reach temperatures near absolute zero, making it vital in superconducting magnet systems and MRI scanners.
2. Aerospace and Aviation
- Used in space applications to purge rocket fuel tanks and as a coolant for satellite and spacecraft components.
3. Semiconductor Manufacturing
- Helium’s thermal conductivity and inert nature make it ideal for cooling high-performance electronics and plasma etching in chip fabrication.
4. Leak Detection
- Because helium atoms are so small, they are used in precision leak detection for vacuum systems, nuclear reactors, and refrigeration units.
5. Medical Applications
- Helium gas is blended with oxygen to treat respiratory conditions like asthma and COPD.
- It’s also used in MRI machines for maintaining superconducting magnets.
6. Welding
- Helium is used as a shielding gas in arc welding, especially for aluminum, stainless steel, and other non-ferrous metals.
7. Scientific Research
- Helium-1 is essential in particle accelerators and low-temperature physics experiments due to its stability and low boiling point.

Helium vs. Helium-1: Understanding the Difference
There is often confusion between general helium gas and the term “Helium-1.” Here’s how to differentiate them:
- Helium (He): Refers to the element in general, used in balloons, cooling, and more.
- Helium-1 (He I): The form of helium used above 2.17 Kelvin, typically in cryogenic and scientific applications.
- Helium-2 (He II): Superfluid helium used below the lambda point for advanced cryogenic systems.
Safety and Storage Guidelines
While helium is generally safe, proper handling and storage are crucial:
- Store helium cylinders upright in a cool, well-ventilated area.
- Keep away from high heat and open flames (though helium is non-flammable, high pressure can be dangerous).
- Always use a regulator and secure the cylinder during transport and use.
- Never inhale helium – while often used for voice alteration, it can displace oxygen and cause asphyxiation.
