Precision Ar-He Gas Blend — exact argon-helium ratios, certified and repeatable
A Precision Ar-He Gas Blend from REAL GAZ pairs argon with helium at a tightly controlled ratio, for users whose results depend on thermal conductivity, ionisation behaviour or arc characteristics staying constant.
Because helium is light and argon is heavy, careful preparation matters: each cylinder is blended by weight and mixed thoroughly so the fraction at the last litre matches the first.
Because helium is light and argon is heavy, careful preparation matters: each cylinder is blended by weight and mixed thoroughly so the fraction at the last litre matches the first.
Preparation follows ISO 6142-1, with composition confirmed per ISO 6143 and uncertainty stated in the accompanying analysis report under ISO 17025-based procedures.
Typical precision ratios include 1%, 5%, 10%, 25% and 50% helium in argon, supplied in 10-litre and 50-litre cylinders at 150 or 200 bar. Helium is a small, fast-diffusing atom, so valves, seals and diaphragms should be chosen with this in mind; REAL GAZ fits cylinders with valves tested at helium leak rates appropriate for the application. The certificate gives the helium fraction, the argon balance, the date of preparation and a recommended period within which the value remains valid.
🏭 Where Ar-He Precision Blends Are Used
- 🔬 Detector and plasma sources — analytical instruments use argon-helium to stabilise plasmas and tune detector response;
- 🧲 Leak detection reference — helium-bearing mixtures serve as test gas for checking sealed components and vacuum equipment;
- 💎 Crystal and fibre production — controlled thermal conditions in furnaces are managed with argon-helium atmospheres;
- 🚀 Laser processing — the mixture assists in beam delivery and plume control during metal and ceramic processing.
💡 Why Choose REAL GAZ
- ✅ Exact ratios — helium percentages are held to a narrow tolerance, giving repeatable instrument and process behaviour;
- 🧪 Homogeneity assured — cylinders are rolled and left to equilibrate before analysis, preventing stratification;
- 🎯 Documented uncertainty — the certificate states the composition and its expanded uncertainty for your quality file;
- 🔒 Long shelf life — internally treated cylinders and clean valves keep helium content stable in storage;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- helium and argon purity verification;
- gravimetric blending on calibrated balances;
- homogenisation by rolling before analysis;
- helium leak test of cylinder and valve.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
Use stainless-steel or brass regulators with metal diaphragms for mixtures that will be used in sensitive analysis. After connecting a new cylinder, purge the line several times before collecting data. Keep the cylinder at stable temperature and above the minimum pressure stated on the certificate.
