High purity liquid argon is an ultra-pure cryogenic gas used in demanding industrial applications. It is regulated by the standard GB/T 4842-2017 and has a remarkable purity level of 99.999%. This ultra-high purity ensures minimal impurities, making it suitable for applications where even trace contaminants could have significant adverse effects. It is typically supplied in two main forms: tank gas supply and Dewar gas supply, both of which facilitate large-scale storage and transportation.

Detailed Description
High purity liquid argon is an inert gas with an ultra-high purity level of 99.999%. Its inert nature and extremely low boiling point (-186°C) make it an ideal gas for applications requiring a contaminant-free environment. This level of purity is crucial in industries such as aerospace, electronics, and medical research, where even trace amounts of impurities can affect the performance and reliability of materials and processes.
Applications
Aerospace: High purity liquid argon is used for cryogenic testing of rocket components and as a shielding gas in the manufacturing of high-performance materials. Its inert properties ensure that sensitive components remain uncontaminated during production and testing.
Electronics: In semiconductor manufacturing, high purity liquid argon is used to create an inert atmosphere during processes such as chemical vapor deposition (CVD) and physical vapor deposition (PVD). This helps prevent oxidation and contamination, ensuring the production of high-quality electronic components.
Medical Research: Liquid argon is used in cryogenic applications such as cryotherapy and the preservation of biological samples. Its ultra-high purity ensures that these sensitive processes are not compromised by contaminants.
Metal Production and Welding: High purity liquid argon is used as a shielding gas in welding processes, such as gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW). It provides a stable and inert atmosphere, preventing oxidation and ensuring high-quality welds.
Supply Forms
High purity liquid argon is typically supplied in two forms: tank gas supply and Dewar gas supply. Tank gas supply is ideal for large-scale industrial operations, providing a continuous and reliable source of gas. Dewar gas supply, on the other hand, offers flexibility and portability, making it suitable for applications where the gas needs to be transported to different locations or used in mobile setups.
Regulatory Compliance
Compliance with GB/T 4842-2017 ensures that high purity liquid argon meets strict purity and safety standards. Regular testing and quality control measures are implemented throughout the production process to guarantee that each batch of liquid argon meets the required specifications.
