As a supplier of standard gas, I've been deeply involved in the industry, and one question that frequently arises is: What are the sources of standard gas? In this blog, I'll explore the various sources of standard gas, shedding light on how these essential substances are produced and sourced.
Natural Gas Extraction
One of the primary sources of standard gas is natural gas extraction. Natural gas is a mixture of hydrocarbons, primarily methane, along with small amounts of other gases such as ethane, propane, and butane. When extracting natural gas from underground reservoirs, it often contains impurities that need to be removed to meet the high - purity standards required for standard gas.
The process begins with the drilling of wells into natural gas reservoirs. Once the gas is brought to the surface, it undergoes a series of purification steps. These steps include removing water vapor, hydrogen sulfide, and other contaminants. The purified natural gas can then be used as a base for producing standard gas mixtures. For example, methane from natural gas can be used to create standard gas mixtures for calibration of gas analyzers in the oil and gas industry.
Chemical Synthesis
Chemical synthesis is another important source of standard gas. Through chemical reactions, specific gases can be produced with high purity. For instance, hydrogen standard gas can be produced through the electrolysis of water. In this process, an electric current is passed through water, splitting it into hydrogen and oxygen. The hydrogen gas produced can be further purified to meet the standards required for use as a standard gas. You can find more information about Hydrogen Standard Gas on our website.
Another example is the synthesis of sulfur hexafluoride gas. Sulfur hexafluoride is a highly stable and non - flammable gas, widely used in electrical insulation and as a tracer gas. It is produced by reacting sulfur with fluorine under controlled conditions. The reaction is carefully monitored to ensure the production of high - purity sulfur hexafluoride.

Air Separation
Air separation is a well - established method for obtaining standard gases such as nitrogen, oxygen, and argon. The air we breathe is a mixture of various gases, and through the process of air separation, these gases can be separated and purified.
The most common method of air separation is cryogenic distillation. In this process, air is first compressed and cooled to extremely low temperatures. As the air cools, different components condense at different temperatures. Nitrogen, which has a lower boiling point than oxygen, can be separated from the liquid air. The separated nitrogen can then be further purified to produce high - purity nitrogen, which is widely used as a standard gas in many industries.

Gas Recycling and Re - purifying
In addition to the above sources, gas recycling and re - purifying also play an important role in the production of standard gas. In many industrial processes, gases are used and then released into the environment. However, some of these gases can be collected, recycled, and re - purified to be used as standard gas.
For example, in the semiconductor manufacturing industry, a large amount of nitrogen is used for purging and protecting the manufacturing environment. After use, the nitrogen can be collected and re - purified to remove any contaminants. This recycled nitrogen can then be used as a standard gas, reducing the cost and environmental impact of gas production.
Quality Control in Standard Gas Production
Regardless of the source of standard gas, strict quality control is essential to ensure the accuracy and reliability of the gas. Quality control measures include regular calibration of production equipment, testing of gas samples, and compliance with international standards.
Before a batch of standard gas is released to the market, it undergoes a series of tests to determine its composition, purity, and stability. These tests are carried out using advanced analytical instruments, such as gas chromatographs and mass spectrometers. Only when the gas meets the specified standards can it be labeled as standard gas and sold to customers.
The Importance of Standard Gas in Various Industries
Standard gas plays a crucial role in many industries. In the environmental monitoring industry, standard gas is used to calibrate gas analyzers, ensuring accurate measurement of pollutants in the air. In the medical industry, standard gas is used for calibration of medical gas analyzers, which are essential for patient safety. In the industrial manufacturing industry, standard gas is used for process control and quality assurance.
Conclusion
In conclusion, the sources of standard gas are diverse, including natural gas extraction, chemical synthesis, air separation, and gas recycling. Each source has its own advantages and challenges, and the choice of source depends on factors such as the type of gas required, the purity level, and the cost.
