Precision Nitrous Oxide Gas — accurate N₂O for measurement and calibration
Precision nitrous oxide gas is used where the figure on the certificate becomes the figure on the instrument. REAL GAZ prepares N₂O with controlled purity, and as a gravimetrically blended standard in nitrogen or air at ppm and percent levels.
Analytical uncertainty is stated on the CoA so your own calibration chain remains transparent.

Preparation follows ISO 6142-1 gravimetric methods, verification follows ISO 6143, and laboratory work is performed under ISO 17025 principles for laboratory and industrial users.
Reliable low-level standards depend on the surface of the cylinder. Nitrous oxide is relatively stable, but at ppm and sub-ppm levels it can interact with untreated steel walls, so we use aluminium or specially conditioned cylinders with stainless steel diaphragm valves for the most sensitive mixtures. Stability is confirmed by repeat analysis over time before a shelf life is stated.
🏭 Where Nitrous Oxide Are Used
- ⚙️ Greenhouse-gas analysers — N₂O reference standards calibrate GC-ECD and laser analysers used in climate and agricultural studies;
- 🔬 Stack emission monitoring — plants check continuous analysers against known N₂O concentrations;
- 🏥 Process analytics — chemical producers verify online sensors where N₂O is a by-product;
- 🚀 Research laboratories — scientists need known concentrations to validate detection limits.
💡 Why Choose REAL GAZ
- ✅ Gravimetric accuracy — mixtures are weighed on high-resolution balances with traceable masses;
- 🧪 Stability data — shelf life is stated and based on the cylinder and valve combination used;
- 🎯 Certified values — uncertainty is reported at a defined coverage level;
- 🔒 Passivated cylinders — treated internal surfaces reduce adsorption at low concentrations;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- balance calibration against traceable reference weights;
- mixture verification against independent standards;
- homogenisation by rolling before dispatch;
- valve and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📐 Typical Concentration Ranges
- 1 ppm to 1,000 ppm N₂O in nitrogen for environmental work;
- 1 % to 20 % N₂O for process analyser spans;
- balance gas in nitrogen or synthetic air as specified;
- cylinder sizes from 5 to 50 litres, with pressure up to 150 bar for mixtures.
Customers who need traceability to national standards can request certificates that state the reference materials used for verification. Use mixtures within the stated shelf life, keep cylinders at stable room temperature and flush the regulator with the mixture before taking readings. These simple habits protect the accuracy you paid for.
