Precision Argon Helium Mixture — calibrated blends with certified composition for analysis and process control
A precision argon helium mixture is prepared by weighing each component into the cylinder, rather than by pressure or flow estimates, so the composition printed on the certificate is traceable and reproducible. REAL GAZ prepares helium-in-argon and argon-in-helium blends from 100 ppm up to 50% in 5, 10, 20 and 50 litre cylinders.
Each cylinder is homogenised by rolling, analysed against reference standards and released with a stated expanded uncertainty.
Each cylinder is homogenised by rolling, analysed against reference standards and released with a stated expanded uncertainty.
Preparation follows ISO 6142-1 for gravimetric blending and ISO 6143 for comparison and calibration, with analytical work performed to ISO 17025 principles for quality labs and process plants.
🏭 Where Argon-Helium Mixtures Are Used
- 🔍 Helium leak testing — trace helium in argon is used to test vacuum chambers, heat exchangers and sealed components where pure helium would be wasteful;
- 🔬 Analyser calibration — thermal conductivity and mass spectrometer instruments are set against a known argon-helium reference point;
- 🏭 Inert atmosphere control — glove boxes and furnaces use a measured blend to tune thermal behaviour and heat transfer;
- 📡 Plasma and lighting research — controlled ratios influence ionisation, arc stability and spectral output in experimental setups;
💡 Why Choose REAL GAZ
- 📏 Traceable composition — each blend is weighed on calibrated balances so results can be defended in an audit;
- 🧪 Wide concentration range — from low ppm leak-test levels to percent-level process blends, all prepared in-house;
- 🎯 Stable over time — cylinder treatment and valve selection minimise adsorption, so stated values hold through the shelf life;
- 🔒 Clear labelling — composition, uncertainty, pressure and expiry are printed on each cylinder tag;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- pure argon and helium sources analysed before blending;
- gravimetric weighing with documented balance calibration;
- post-blend analysis against independent standards;
- valve leak check and final pressure verification.
Cylinders are aluminium or steel built to ISO 7866 or ISO 9809, and consignments follow ADR / UN transport rules.
📏 Understanding Mixture Accuracy
A certificate for a precision blend lists the nominal composition, the gravimetric value, the analytical result and an expanded uncertainty, usually quoted at a 95% confidence level. For leak detection work a relative tolerance of 5% is common, while calibration of thermal conductivity analysers often requests 1 to 2%. Please tell us which tolerance your procedure demands, because tighter values need more careful preparation and a longer lead time. Store cylinders at stable room temperature, avoid using them below 10 bar where adsorption effects grow, and keep the supplied tag with the cylinder so results can be traced during future audits.
⚙️ Trusted Gas Solutions
REAL GAZ delivers each precision argon helium mixture to testing laboratories, manufacturers and research bodies across Azerbaijan, Turkey, Georgia and Uzbekistan, and ships to American clients on request. Share your target concentration and tolerance, and we will confirm what is achievable before the cylinder is prepared.
