Specialty Gas Cylinders — Purpose-Prepared Cylinders for Demanding Gases
Specialty gas cylinders are prepared differently from standard cylinders, because trace-level purity and mixture stability depend on the inner surface. REAL GAZ offers aluminium and treated steel cylinders that are evacuated, conditioned and filled for high-purity gases and certified mixtures.
Reactive components such as sulphur compounds, nitrogen oxides and low-level moisture are held in cylinders chosen for their stability.
Reactive components such as sulphur compounds, nitrogen oxides and low-level moisture are held in cylinders chosen for their stability.
Mixtures are prepared following ISO 6142 and verified under ISO 6143, with laboratory competence aligned to ISO 17025, for analytical and process customers.
🏭 Where Specialty Cylinders Are Used
- ⚙️ Calibration of analysers — emission, ambient air and process analysers are checked with certified mixtures at stated concentrations;
- 🔬 Semiconductor and electronics — high-purity and electronic-grade gases need clean wetted surfaces and dry delivery lines;
- 🏥 Environmental monitoring — trace gas standards support stack testing and air quality stations;
- 🚀 Research institutes — bespoke blends and rare gases are supplied in small cylinders for experiments.
💡 Why Choose REAL GAZ
- ✅ Internal surface treatment — passivation and conditioning keep reactive trace components stable;
- 🧪 Compatible valves — stainless steel diaphragm valves limit diffusion and back-contamination;
- 🎯 Stated uncertainty — mixture certificates show composition and expanded uncertainty;
- 🔒 Shelf-life guidance — each mixture carries a validity period based on stability data;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- vacuum bake-out and conditioning of cylinders;
- gravimetric preparation on calibrated balances;
- analytical verification against reference standards;
- leak testing of valves and outlets.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
🧪 Selecting the Right Cylinder
Tell us the gas or mixture, concentration range, accuracy you need and the equipment it will feed. Aluminium cylinders suit many reactive mixtures, while higher-pressure steel cylinders offer more gas for stable components. Purge regulators and lines before connecting, use dedicated regulators for each gas family, and avoid draining a mixture below 10 bar, since low pressure can alter the composition drawn off. Typical product families include calibration mixtures of CO, CO₂, NO, SO₂ and hydrocarbons in nitrogen or air, ultra-pure helium, hydrogen and argon, and electronic gases requested by individual project. Volumes run from 0.5 litre pocket cylinders to 50 litre cylinders, and tailor-made concentrations are agreed before blending. Delivery lead times depend on the component, so please send enquiries early, together with the application and required uncertainty.
