High Purity SO₂ Distributor — high-assay SO₂ with controlled impurities
As a High Purity SO₂ Distributor, REAL GAZ delivers sulfur dioxide with tightly controlled water, SO₃ and non-condensable impurities.
Grades of 99.9% and higher can be requested for demanding synthesis and instrument work.
Grades of 99.9% and higher can be requested for demanding synthesis and instrument work.
Purity data are supported by ISO 17025-based analytical methods and cylinder cleanliness practice per EN ISO 11114, serving research and electronics customers.
🏭 Where High Purity SO₂ Is Used
- 💻 Materials research — reactive gas studies on thin films and surface chemistry;
- ⚗️ Fine chemicals — pharmaceutical intermediate work that is sensitive to trace water;
- 🔋 Energy storage — experimental lithium–SO₂ cell electrolytes;
- 🛰️ Atmospheric simulation — chamber experiments on sulfate aerosol formation.
💡 Why Choose REAL GAZ
- ✅ Impurity transparency — specific impurity values are reported where measured;
- 🧪 Clean cylinder preparation — treated surfaces keep the assay stable in storage;
- 🎯 Technical matching — we help select the grade needed, avoiding over-specification;
- 🔒 Controlled distribution — secure packing and handling from fill to your dock;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- multi-stage purification and drying;
- trace moisture measurement;
- gas chromatographic impurity profiling;
- leak tightness verification.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Purity Control & Applications
High purity sulfur dioxide is sensitive to moisture, air and metal contamination. Cylinders are evacuated, conditioned and filled through clean, dedicated lines, and the final product is analysed for water, SO₃, carbon dioxide and permanent gases where required by the customer.
Users should employ stainless steel, electropolished tubing with metal-sealed fittings where possible, and purge with high purity inert gas before introducing SO₂. Dead legs, elastomer seals and plastic tubing can all release moisture and distort results. REAL GAZ can recommend a point-of-use purifier or a dedicated regulator for critical work. Distribution is planned to keep the time between fill and use short, so that the certified assay is still representative when the cylinder is opened.
Customers working at the boundary of detection limits should discuss method requirements with us at the quotation stage. We can note the key impurities of concern, propose an appropriate analytical check and suggest a supply schedule that minimises storage time, so that your measurements are not affected by ageing of the contents. Ask us about dedicated cylinders for repeat high purity orders; reserving the same vessels for the same gas avoids cross-contamination and gives more consistent results across successive deliveries.
