High Purity Heliox for laboratory — tightly controlled helium–oxygen for analytical work
Researchers who need High Purity Heliox for laboratory use want a blend whose helium and oxygen are free from hydrocarbons, water and other contaminants that could bias a measurement.
REAL GAZ prepares these mixtures from high-grade helium and oxygen, typically 5.0 helium and 4.5 oxygen feedstock, then verifies the finished composition on calibrated analysers.

Blending is carried out according to ISO 6142, composition is checked following ISO 6143, and our analytical approach reflects ISO 17025 for laboratory and research customers.
🏭 Where High Purity Heliox Are Used
- 🔬 Instrument calibration — oxygen analysers, paramagnetic sensors and mass spectrometers need reference gas of known composition;
- 🧬 Physiology experiments — studies of respiration and gas exchange require a clean, well-characterised helium–oxygen supply;
- 📈 Gas-flow modelling — experimentalists compare measured flow with computational models using a defined He/O₂ ratio;
- 🧊 Cryogenic and vacuum work — dry, impurity-controlled gas protects cold stages, detectors and sample chambers;
- 🎓 University teaching — laboratory classes demonstrate thermal conductivity and sound speed in gas mixtures.
💡 Why Choose REAL GAZ
- 🧪 Low impurities — moisture, total hydrocarbons and nitrogen are minimised and reported on request;
- ✅ Stated uncertainty — composition is quoted with an uncertainty value you can carry into your own budget;
- 🎯 Flexible ratios — small batches of unusual compositions can be prepared for experiments;
- 🔒 Clean cylinders — internal surfaces are treated and evacuated before each fill to avoid carry-over;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🧫 Using Heliox in the Laboratory
Choose stainless steel or other oxygen-compatible tubing and keep the delivery line short and clean. Purge regulators before connecting, since trapped air will contaminate a high purity blend. Cylinders should settle at room temperature before use, and valves should be opened slowly. Because helium diffuses readily, pay close attention to fitting leaks, which can alter the composition at the point of use more than inside the cylinder.
🔬 Quality Control & Safety
- multi-stage purification of both source gases;
- precision gravimetric blending in evacuated cylinders;
- moisture & impurity analysis by laboratory instruments;
- stability checks on stored sample cylinders;
- leak testing and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards, including ISO 9809 for refillable seamless steel cylinders.
