Helium Gas Mixture S₂+

HELIUM GAS MIXTURE S₂+ — a helium-based blend prepared for repeatable results

Helium Gas Mixture S₂+ from REAL GAZ is a helium-balanced blend prepared for customers who need a stable, well-documented composition from the first cylinder to the last. Helium is chemically inert, has very high thermal conductivity and a low molecular mass, which is why it is chosen as the balance gas for so many analytical and process blends.
Each batch is blended by weight, analysed against traceable reference standards and released only when the result sits within the agreed tolerance for the requested component and balance.

REAL GAZ supplies this product according to ISO 6142, ISO 6143 and ISO 17025 practice, suitable for industrial and laboratory use. Where a customer specification names a different tolerance class, we confirm it in writing before filling.

🏭 Where S₂+ Helium Mixtures Are Used

⚙️ Gas chromatography — helium-balanced blends serve as carrier, make-up or check gas on GC lines in petrochemical and food laboratories;
🔬 Instrument verification — analysts use the blend to confirm response and linearity of detectors between formal calibrations;
🏥 Leak detection — the small helium atom makes the mixture useful for tracing leaks in sealed assemblies and vacuum systems;
🚀 Research and development — university and industrial R&D groups use inert blends for controlled-atmosphere experiments and sensor testing.

💡 Why Choose REAL GAZ

✅ Composition you can trace — every cylinder is linked to a gravimetric record and a named analyst;
🧪 Stable balance gas — helium does not react with typical components, which supports long shelf life when cylinders are stored correctly;
🎯 Tolerance matched to purpose — we discuss uncertainty and component range with you before blending, not after;
🔒 Secure valves and fittings — each cylinder leaves with a tamper-evident seal and the correct outlet connection for the blend;
📄 Certificate of Analysis (CoA) — supplied with every order.

🔬 Quality Control & Safety

multi-stage purification of the helium balance;
precision gravimetric blending on calibrated balances;
moisture & impurity analysis before release;
leak testing and pressure integrity checks on every valve.

Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.

Because helium escapes through very small gaps, we recommend metal-seated or PTFE-sealed connections and a leak check on every new regulator fitting. Customers who run low flows should also allow a short purge before sampling, so that air trapped in the line does not distort the first reading. For long sequences we suggest fitting a dedicated cylinder for each instrument, which avoids repeated disconnection and keeps the baseline stable. Our dispatch team packs every order with protective caps, checks the cylinder label against the order and attaches the analysis certificate, so that goods can be received and put into service without delay. If you are unsure which specification is appropriate, a short call with our technical staff will usually settle the question before any gas is blended.

⚙️ Trusted Gas Solutions

REAL GAZ supplies Helium Gas Mixture S₂+ to customers in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA, with cylinders sized to suit laboratory benches and plant gas rooms alike. Our team will help you choose between small portable cylinders and larger packs, advise on regulators with suitable diaphragm materials, and explain safe handling of helium, including the risk of oxygen displacement in poorly ventilated rooms. Store cylinders upright, secured and away from heat, and keep valve outlets clean and capped when not in use.

REAL GAZ — helium blends you can document and trust.
