Specialty Gas Ar-He — application-grade argon-helium from a specialist supplier
Specialty Gas Ar-He from REAL GAZ is an argon-helium mixture treated as a specialty product: high-purity components, tested cylinders and a full composition record rather than a bulk-commodity fill.
It is intended for scientific, electronic and high-value manufacturing tasks where impurities of even a few parts per million can change the outcome.
It is intended for scientific, electronic and high-value manufacturing tasks where impurities of even a few parts per million can change the outcome.
Our specialty range is prepared in accordance with ISO 6142-1, verified per ISO 6143 and filled into cylinders cleaned to the requirements of EN ISO 11114 material-compatibility practice.
Specialty lots are filled from 5.0 or 6.0 grade components into cylinders that have been evacuated, baked or purged to remove moisture, and each lot is sampled for oxygen, water and total hydrocarbons. Helium contents are offered from parts-per-million spikes up to helium-rich blends, in aluminium cylinders where a lightweight vessel is preferred or in steel cylinders where higher pressure is needed. Where an instrument manufacturer specifies a gas quality, we can compare it against our analysis before you buy.
🏭 Where Ar-He Specialty Mixtures Are Used
- 🧫 Semiconductor research — argon-helium environments are used in thin-film deposition and plasma etch development;
- 🔭 Scientific instruments — spectrometers and gas analysers draw on low-impurity Ar-He as a plasma or purge gas;
- 🧬 Materials testing — thermal-analysis furnaces need an inert atmosphere with defined heat-transfer behaviour;
- 🛰️ Aerospace components — additive-manufacturing chambers and high-value welding cells rely on clean inert mixtures.
💡 Why Choose REAL GAZ
- ✅ High-purity starting gases — argon and helium of 5.0 purity or above reduce trace contamination;
- 🧪 Specialty cylinder treatment — internal surfaces are prepared to limit moisture and hydrocarbons adsorbing onto walls;
- 🎯 Application support — our team helps you choose the helium fraction for your instrument or process;
- 🔒 Stable supply chain — regular lots of the same composition mean results stay comparable between deliveries;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- trace-impurity analysis on each lot;
- cylinder evacuation and purging before filling;
- gravimetric preparation and verification;
- pressure integrity and valve leak checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
For best results, connect through a purge-capable regulator and stainless-steel tubing with metal-sealed fittings. Avoid plastic tubing, which allows helium and moisture to permeate. Always cap the cylinder outlet immediately after disconnecting to prevent contamination of the valve seat.
