Precision Hydrocarbon Gas Blend — accurate flammable standards, safely handled
A Precision Hydrocarbon Gas Blend from REAL GAZ combines components such as methane, ethane, propane and butane in a gravimetrically prepared mixture with a certified composition.
These blends are flammable, so preparation, cylinder choice and labelling are handled with particular care, and dew-point limits are considered for heavier components.

REAL GAZ supplies this product according to ISO 6142-1, ISO 6143, ISO 6974 for natural gas analysis and ISO 6976 for calorific value calculation, suitable for energy, petrochemical and laboratory users.
🏭 Where Hydrocarbon Gas Blends Are Used
- ⚙️ Natural gas analysis — calibrating chromatographs that determine composition and calorific value;
- 🔬 Refinery laboratories — reference blends for light-end analysis of process streams;
- 🏥 Gas detector calibration — verifying combustible gas sensors at defined percent-LEL points;
- 🚀 Fuel and burner testing — known compositions used in combustion research and appliance trials.
💡 Why Choose REAL GAZ
- ✅ Gravimetric accuracy — each component weighed and verified;
- 🧪 Dew-point awareness — concentration limits observed so heavier components remain gaseous;
- 🎯 Matched to the method — component list follows your analytical method;
- 🔒 Safety guidance — handling advice for flammable mixtures included;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📦 Specifications and Supply
- Components typically methane to pentane, others on request;
- Cylinders with valves suited to flammable gas service;
- Concentrations from low ppm to percent level;
- Ventilated, ignition-free storage recommended.
Keep flammable cylinders away from ignition sources, use suitable regulators and earth equipment where needed. Heavier hydrocarbons can condense at low temperature, so store and use the cylinder at stable temperature.
Hydrocarbon standards are chosen to bracket the range expected in your samples. For natural gas work, a typical standard contains methane as the balance with ethane, propane, butanes and sometimes pentanes at lower levels, along with nitrogen and carbon dioxide. Because dew point rises with pressure and with heavier components, the mixture is designed so that nothing condenses at normal storage temperature. Heated regulators or lines may be advised for the heaviest blends. Please tell us your method, instrument and expected sample range, and we will propose a composition rather than expecting you to design it from scratch. Certificates for flammable standards also list the cylinder volume, the fill pressure and the recommended minimum usable pressure, because the last portion of a cylinder may not represent the certified composition.
🔬 Quality Control & Safety
- multi-stage purification;
- precision gravimetric blending;
- moisture & impurity analysis;
- leak testing and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
