Specialty Gas N₂O — high-purity nitrous oxide for demanding work
Specialty Gas N₂O from REAL GAZ is high-purity nitrous oxide, typically 99.9% to 99.998%, prepared with tight control of nitrogen, oxygen, carbon dioxide and water impurities.
This grade suits users whose results change if the oxidant carries trace contamination, such as thin-film engineers, isotope researchers and instrument manufacturers.
This grade suits users whose results change if the oxidant carries trace contamination, such as thin-film engineers, isotope researchers and instrument manufacturers.
Analysis is performed with methods consistent with ISO 17025, ISO 6142-1 for blends and ISO 19229 purity assessment, for research and microelectronics customers.
Purity matters because small contaminants can have outsized effects. Water vapour in N₂O interferes with deposition chemistry and instrument baselines, nitrogen dilutes oxidant concentration, and carbon dioxide or trace hydrocarbons can show up as spurious signals in sensitive detectors. Specialty cylinders are therefore prepared with evacuation, repeated purge cycles and, where needed, aluminium or treated-steel interiors that limit adsorption.
🏭 Where Specialty N₂O Is Used
- ⚙️ Atmospheric chemistry — N₂O is measured as a greenhouse gas, and pure N₂O prepares calibration standards for monitoring networks;
- 🔬 Isotope studies — stable-isotope laboratories use N₂O in analytical method development;
- 🏥 Thin-film deposition — low-moisture N₂O supports reproducible silicon oxide and oxynitride growth;
- 🚀 Gas-mixture blending — pure N₂O is the base for calibration mixtures in nitrogen or synthetic air.
💡 Why Choose REAL GAZ
- ✅ Certified impurities — a CoA lists each trace impurity measured and the method used;
- 🧪 Stainless-steel path — fill lines are passivated to protect purity;
- 🎯 Dedicated high-purity cylinders — treated interiors reduce moisture retention;
- 🔒 Batch consistency — repeat orders match earlier lots closely;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- multi-stage purification and cryogenic trapping;
- gas chromatography with TCD and ECD detection;
- dew point monitoring in the fill system;
- double leak testing for helium and pressure tightness.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
⚙️ Trusted Gas Solutions
REAL GAZ supplies Specialty Gas N₂O to environmental monitoring bodies, universities and manufacturers in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Contact us with your required impurity limits and we will confirm the matching specification before filling.
We recommend stainless-steel diaphragm regulators with metal seals and a short, leak-tested line made of electropolished tubing, since plastic hose lets moisture back in. Typical packaging includes 10, 20 and 40 litre cylinders, and the exact fill is stated in kilograms on the certificate so that you can plan consumption against purity. Cylinders are shipped with protective caps, tamper seals and a label showing grade, net weight and fill date. Please quote the intended instrument or process when ordering, so that we can confirm that the material of the cylinder valve and the purity level suit your application, and avoid paying for a specification you do not need.
