Laboratory N₂O Gas — nitrous oxide for analytical instruments
Laboratory N₂O Gas from REAL GAZ is supplied in compact cylinders for analytical laboratories that run atomic absorption spectrometers and similar instruments.
The gas is dried and analysed so that flame stability and detection limits are not affected by contamination, and it is supplied with the guidance that a heated regulator prevents freezing.

Supply is aligned with ISO 17025 record keeping, EN ISO 11114 material compatibility and ADR / UN 1070, for analytical and academic laboratories.
Day-to-day operation of a nitrous oxide flame is simple when the supply is correct. Set the delivery pressure recommended by the manufacturer, usually 3 to 4 bar, confirm that the regulator is heated or that its body is warm to the touch, and make sure that hoses are rated for nitrous oxide. During long runs of many samples, a stable gas pressure maintains consistent absorbance readings and reduces the need for recalibration.
🏭 Where N₂O Is Used
- ⚙️ Flame AAS of refractory metals — the hotter nitrous oxide–acetylene flame frees aluminium, barium, vanadium and zirconium from oxides;
- 🔬 Soil and ore analysis — geochemical laboratories determine silicon and titanium in digested samples;
- 🏥 Teaching laboratories — students learn flame atomisation with controlled, labelled cylinders;
- 🚀 Method development — analysts compare flame types to optimise sensitivity and interference removal.
💡 Why Choose REAL GAZ
- ✅ Flame stability — consistent purity keeps burner conditions steady across long sequences;
- 🧪 Regulator guidance — we recommend heated N₂O regulators to avoid freeze-up at high flow;
- 🎯 Compact cylinders — sizes suit the limited space of instrument rooms;
- 🔒 Safety documents — SDS and handling notes accompany every cylinder;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- fill line purge and dedicated cylinders;
- moisture control with low-dew-point gas;
- weighing to the correct filling ratio;
- check of valve seat and outlet thread.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
⚙️ Trusted Gas Solutions
REAL GAZ delivers Laboratory N₂O Gas to testing laboratories, mining and geochemistry groups and universities in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Keep acetylene and N₂O lines separate, use flashback arrestors and follow your spectrometer maker's start-up sequence.
Because the flame is hotter than the air-acetylene flame, burner heads, nebulisers and spray chambers may suffer deposits, and keeping them clean extends their life. Ask us about spare regulators, tubing, flashback arrestors and wall brackets to complete your setup and keep one spare cylinder ready for continuous work.
