Specialty Gas Helium — ultra-high-purity helium for analytical science
Specialty Gas Helium from REAL GAZ covers purity grades of 99.9999 % and above, together with certified helium mixtures used for calibration and detection. In analytical instruments even a few ppm of oxygen, water or hydrocarbons can raise baselines or shorten column life.
Our cylinders are cleaned, evacuated and filled using dedicated lines to protect this purity.

REAL GAZ supplies this product according to ISO 6142 for mixtures, ISO 17025 analysis and EN ISO 14175 for welding blends, suitable for laboratory and high-technology industrial use.
🏭 Where Specialty Helium Is Used
- 📈 Gas chromatography — carrier gas for GC and GC-MS with low detector noise;
- 🧬 ICP-MS — collision and reaction cell gas to reduce polyatomic interferences;
- ❄️ Cryogenic research — cooling of superconducting magnets and low-temperature physics experiments;
- 🚀 Aerospace testing — pressurisation, purge and leak tests of precision components.
💡 Why Researchers Choose REAL GAZ
- ✅ Ultra-low impurities — oxygen, water and total hydrocarbons are reported in ppm or ppb;
- 🧪 Dedicated cylinders — treated interiors prevent desorption of contaminants;
- 🎯 Mixture capability — helium blends with neon, nitrogen or target analytes on request;
- 🔒 Supply continuity — scheduled deliveries protect long-running experiments;
- 📄 Certificate of Analysis (CoA) — supplied with every order
🔬 Quality Control & Safety
- multi-stage purification and gettering;;
- trace impurity analysis;;
- gravimetric blending for mixtures;;
- leak and pressure integrity checks.
Fit a high-purity regulator with a metal diaphragm and purge the line before use to keep specified purity at the point of use.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Purity in Practice
Maintaining the stated purity depends on the whole gas path. Use a two-stage regulator with a metal diaphragm, stainless steel tubing that has been baked or purged, and an inline trap for oxygen and moisture where required. Replace cylinders before they reach the lowest pressure, since residual gas can contain a higher fraction of impurities, and keep a log of lots used for each analytical sequence.
- use all-metal seals for ppb-level work;
- leak-check connections with helium itself;
- purge the regulator several times after connection;
- keep cylinders away from vibration near sensitive instruments.
Mixtures broaden the options. REAL GAZ prepares helium blends with neon, nitrogen, oxygen or trace hydrocarbons for detector tuning and calibration, with certified concentration and uncertainty in line with ISO 6142, so one supplier can cover both carrier gas and standards. Please share the instrument model and the method requirements when you enquire, and we will confirm the purity grade, regulator type and cylinder size that suit it.
