Hydrocarbon Gas for Analysis — reference standards for dependable results
Hydrocarbon gas for analysis is the reference material that analysts rely on to calibrate chromatographs, flame ionisation detectors and calorimeters.
REAL GAZ prepares these standards gravimetrically, with component ranges that mirror real samples such as natural gas, refinery fuel gas and landfill gas.

🏭 Where Analytical Hydrocarbon Gases Are Used
- ⚙️ Natural gas analysis — multi-level standards support compositional analysis and heating value calculation in transmission and distribution networks;
- 🔬 FID response factors — single hydrocarbons at ppm level establish detector linearity and carbon response;
- 🏥 Indoor air studies — low-level methane and propane references help verify portable gas detectors and leak surveys;
- 🚀 Biogas and landfill — blends with carbon dioxide and nitrogen replicate the matrix of digester and landfill samples.
💡 Why Choose REAL GAZ
- ✅ Matrix-matched standards — balance gas and component levels are chosen to resemble your sample;
- 🧪 Low uncertainty — gravimetric preparation keeps expanded uncertainty small enough for regulatory reporting;
- 🎯 Several levels — a ladder of concentrations enables multipoint calibration in a single order;
- 🔒 Shelf-life stated — stability is documented so that you know how long the standard can be used;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- verification of each cylinder against a reference standard;
- precision gravimetric blending;
- moisture and impurity analysis of the balance gas;
- leak testing and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards, with passivated internal surfaces for low-ppm stability.
⚙️ Trusted Gas Solutions
REAL GAZ provides hydrocarbon gas for analysis to testing laboratories, gas utilities and environmental agencies in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Share your method number, target components and concentration window, and our team will propose the cylinder size, regulator material and valve outlet that fit your instrument.
For ppm-level standards we recommend stainless steel regulators with a dead-volume-free purge, because plastic diaphragms and long soft tubing can absorb heavier hydrocarbons and bias early injections. A short flush before the first run is good practice, and the certificate lists the minimum usable pressure below which the composition should no longer be trusted.
Selecting the right standard starts with the sample. A typical pipeline gas calls for a six- to ten-component natural gas standard, a refinery fuel gas analysis needs olefins and hydrogen too, and an environmental VOC survey may require a dozen aromatics and light alkanes at low ppb. We help you build a calibration plan with a zero gas, a mid-range level and a span level, so the working range of your detector is fully covered and every result can be traced back to a certified value.
