Specialty SO₂ Gas Mixture — custom blends for demanding applications
Specialty sulfur dioxide mixtures are blended to order by REAL GAZ. Our Specialty SO₂ Gas Mixture service lets you define the component, the concentration and the balance gas, from simple binary blends to multi-component mixtures with CO, NO or CO₂.
Each mixture is validated before release and documented on a certificate of analysis.

REAL GAZ supplies this product according to ISO 6142, ISO 6143, ISO 16664 and ISO 17025, suitable for industrial and laboratory use.
Mixtures can be prepared in nitrogen, air, argon or helium, with SO₂ from low ppm to several percent. Where the application needs several components, such as SO₂, NO, CO and CO₂ in nitrogen, we blend all of them in a single cylinder and certify each one separately.
🏭 Where Specialty SO₂ Mixtures Are Used
- 🔥 Combustion testing — simulated flue gas for burner tuning and scrubber development;
- 🧫 Materials exposure — corrosion chambers following sulfur dioxide test procedures for coatings and metals;
- ⚗️ Catalyst research — feed streams for desulfurisation and SO₂ oxidation studies;
- 🌍 Environmental compliance — reference mixtures for continuous emission monitoring systems.
💡 Why Choose REAL GAZ
- ✅ Made to your recipe — define components, ranges and balance gas rather than settling for stock items;
- 🧪 Compatible cylinders — internal treatment is selected for the reactive components in your blend;
- 🎯 Realistic tolerances — we advise on what concentration accuracy is achievable at your level;
- 🔒 Stability checked — reactive pairs are assessed so you receive a mixture that holds its composition;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- recipe review before any filling begins;
- precision gravimetric blending, component by component;
- analysis of finished mixture against reference standards;
- leak testing and pressure integrity checks.
Some component combinations react inside the cylinder or condense at low temperature. Our technical team checks compatibility, dew point and minimum storage temperature for your recipe and states them with the delivery documents.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
⚙️ Trusted Gas Solutions
REAL GAZ manufactures the Specialty SO₂ Gas Mixture your project needs for customers in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Send your composition and application, and we will confirm feasibility, lead requirements and the certificate format you require.
Typical lead time depends on complexity, so involve us early in the project. We can supply sample certificates, discuss alternative recipes that are easier to stabilise, and recommend cylinder sizes that match your consumption so that a mixture does not sit unused until it expires.
Customers developing new products often begin with a small pilot cylinder to verify a recipe before ordering a production quantity. This keeps cost low, and any change to concentration can be adopted quickly because the blending method is already documented.
REAL GAZ — your composition, our precision.
