🏭 Where Laboratory Helium-Nitrogen Mixes Are Used
- ⚙️ Method development — test blends used while a chromatographic or sensor method is being optimised;
- 🔬 Thermal conductivity detection — helium-rich mixtures give distinct responses against nitrogen in TCD work;
- 🏥 University teaching — safe inert mixtures for demonstrations of gas properties and diffusion;
- 🚀 Materials research — controlled inert atmospheres for small furnaces and glove-box experiments.
💡 Why Choose REAL GAZ
- ✅ Bench-friendly sizes — small cylinders reduce storage burden and waste;
- 🧪 Defined ratios — the helium and nitrogen proportions are verified before release;
- 🎯 Matched to the method — we can align the blend with a published procedure if you provide it;
- 🔒 Safe handling advice — guidance on cabinets, restraint and ventilation for lab use;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📦 Specifications and Supply
- Cylinder volumes from 1 to 10 litres on request, larger sizes also available;
- Typical pressures 100 to 200 bar;
- Ratios stated as mole or volume percent on the certificate;
- Compatible with standard two-stage laboratory regulators.
Always secure cylinders upright with a chain or bracket, and fit a regulator with an appropriate outlet. Ask us if you need help matching a regulator to your laboratory pipework.
Many laboratories buy gas only a few times a year, so documentation matters. Each cylinder is accompanied by a certificate showing the ratio and the cylinder number, and the safety data sheet is available on request in the format your safety officer needs. For teaching laboratories, we can advise on suitable cylinder size so that one cylinder lasts a full term without leaving a large amount of unused gas. For research groups, we can keep a note of previous blends to help repeat a successful experiment. If a method requires a ratio not listed on this page, ask: most requests can be accommodated. If your institution requires purchase documentation, we can provide a clear quotation showing cylinder size, blend specification and certificate type, which makes internal approval easier.
🔬 Quality Control & Safety
- inspection of cylinder test dates and markings;
- controlled filling sequence to avoid stratification;
- verification of composition before release;
- pressure and leak checks of valve and connections.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
