Precision N₂O Gas — accuracy for calibration and measurement
Precision N₂O Gas from REAL GAZ covers high-purity nitrous oxide and carefully prepared N₂O blends at trace concentrations, for users who compare measurements against a known reference.
Blends are made by gravimetric weighing, so the stated concentration, from a few ppb to several percent, can be traced to mass measurements and verified by analysis.
Blends are made by gravimetric weighing, so the stated concentration, from a few ppb to several percent, can be traced to mass measurements and verified by analysis.
Mixtures are prepared under ISO 6142-1, verified per ISO 6143 and reported with ISO 17025 uncertainty, for monitoring and metrology users.
Nitrous oxide has a long atmospheric life and a global-warming potential about 270 times that of carbon dioxide per unit mass, so accurate measurement of its concentration supports climate research and emission inventories. Ambient air contains roughly 330 ppb, and therefore standards at around that level, alongside blends at 1, 10 or 100 ppm for source monitoring, are among the most requested by environmental laboratories.
🏭 Where Precision N₂O Is Used
- ⚙️ Emission monitoring — stack and vehicle-test analysers are checked with N₂O in nitrogen at defined ppm levels;
- 🔬 Atmospheric networks — ppb-level N₂O standards support long-term greenhouse gas measurement;
- 🏥 Agricultural research — soil flux chambers use reference gas to calibrate chromatographs;
- 🚀 Instrument manufacturing — factories verify infrared and photoacoustic analysers before shipment.
💡 Why Choose REAL GAZ
- ✅ Stated uncertainty — each CoA gives concentration with expanded uncertainty;
- 🧪 Stability testing — cylinder treatments keep trace N₂O stable over its shelf life;
- 🎯 Custom concentrations — blends can be made to your target value and balance gas;
- 🔒 Traceability — standards link back to reference masses and calibrated balances;

⚙️ Trusted Gas Solutions
REAL GAZ prepares Precision N₂O Gas for environmental laboratories, calibration bodies and manufacturers in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Send us your concentration, tolerance and cylinder preference and we will propose a suitable specification.
Low-concentration N₂O is vulnerable to adsorption on cylinder walls, so we select cylinder treatments and fill pressures that keep composition stable. Each blend is analysed against reference standards before release, and the certificate states the preparation method, the verified concentration, the uncertainty and the recommended use-by date, which supports your own accreditation records. Where a multi-point calibration is needed, we can prepare a series of cylinders at graded concentrations, such as 50, 100, 250 and 500 ppb, from the same source gas, which keeps the calibration line consistent and simplifies the uncertainty budget for the final result.
REAL GAZ — precision you can trace.
