High Purity Argon Gas - Compressed 99.9999%

Argon gas is available in multiple purity grades ranging from industrial-grade (99.9%) to ultra-high purity (99.9999%, or 6N). The appropriate grade depends on the application — semiconductor sputtering, ICP-MS plasma support, and excimer laser gas mixtures require 5N to 6N purity, while insulated glass fill and general inerting applications may accept lower grades. SpecGas supplies 99.9999% compressed argon.

Yes. Argon 4.7 refers to a purity grade of 99.997% (four nines and a seven), which is considered high purity. It is suitable for many laboratory and analytical applications. However, for more demanding processes such as semiconductor PVD, ICP-MS elemental analysis, or excimer laser gas mixtures, a 5N (99.999%) or 6N (99.9999%) grade like that offered by SpecGas is typically required.

SpecGas offers high purity argon in both disposable and refillable aluminum and steel cylinders. Sizes start at net volumes of 17 liters and scale up to larger quantities for high-volume industrial and laboratory needs. Contact SpecGas directly to discuss specific volume requirements, cylinder configurations, and custom options for your facility.

Applications demanding 99.9999% argon include ICP-MS and ICP-OES plasma support gas for elemental analysis, semiconductor sputtering and PVD process gas, excimer laser (ArF 193 nm) gas mixture components, GC carrier gas in environmental and pharmaceutical labs, and reactive metal melting inerting for titanium and magnesium. Trace impurities at this level can critically compromise analytical accuracy or process yield.

Yes. SpecGas Inc. produces argon gas to NIST-traceable quality standards. This means that purity and concentration values are verifiable against National Institute of Standards and Technology reference materials, providing the documentation required for accredited laboratory operations, instrument calibration, regulatory compliance, and quality management system audits in research and industrial environments.

Yes. High purity argon from SpecGas is used for calibrating welding shielding gas analyzers and blending Ar/CO2 and Ar/He calibration mixtures for TIG and MIG welding applications. Accurate shielding gas calibration is essential to ensure weld quality and compliance with welding procedure specifications. Custom calibration mixtures can also be formulated to match your specific shielding gas ratios.
