TECHNICAL GAS BREATHING MIX — engineered blends for specialist breathing tasks
A technical gas breathing mix from REAL GAZ is a purpose-built blend intended for specialist equipment, trials and non-routine work rather than for general use. Typical examples are helium-oxygen for deep work, nitrogen-lean diluents for rebreathers and low-density mixes for airway-flow research.
Because the composition is the specification, we agree it with you in writing before the first cylinder is filled.

Production references EN 12021 for purity of respirable gas, ISO 6142 for blend preparation and ISO 10286 terminology, supporting engineering and development projects.
Helium is about one seventh as dense as nitrogen, so helium-rich blends move through narrow passages with far less resistance. The same property makes them cool a diver quickly and alters the pitch of the voice. These effects are well documented and are exactly why such mixes need a clear, agreed specification and trained users.
Safety is built into the ordering process. Before we fill, we ask about the maximum operating depth or pressure, the type of breathing equipment and the experience of the users, and we flag any mix that would be unsuitable. This conversation is routine for us and protects both the customer and the integrity of the product we deliver.
🏭 Where Technical Breathing Mixes Are Used
- ⚙️ Rebreather diluent — Technical divers rely on trimix diluent tailored to depth, with a defined end value for narcotic effect;
- 🔬 Flow and acoustics research — Helium-rich mixes lower gas density and are used in wind tunnel and airway model studies;
- 🏥 Saturation and bell systems — Large depth systems need bulk helium-oxygen supplied against a contract specification;
- 🚀 Prototype equipment trials — Manufacturers of new breathing devices test them on blends set well outside everyday air.
💡 Why Choose REAL GAZ
- ✅ Written blend agreement — components, tolerances and cylinder markings are confirmed before filling;
- 🧪 Wide helium capability — helium is held in stock for rapid blending of helium-based mixes;
- 🎯 Low-volume orders — short runs are practical for trials and one-off projects;
- 🔒 Safe cylinder choice — oxygen-rich blends are only filled into cylinders cleaned and rated for them;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- verification of oxygen cleaning before use;
- helium and oxygen fraction analysis after settling;
- homogeneity check by rolling the cylinder before analysis;
- final label check and leak testing.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
