Precision Propane Gas โ tight tolerances for measurement-critical work
Precision propane gas from REAL GAZ is prepared for applications where small variations in composition or concentration affect the result, such as instrument calibration and reference measurement.
Pure propane and propane-in-balance mixtures are blended by weight, so the stated concentration carries a defined uncertainty.

REAL GAZ supplies this product according to ISO 6142-1, ISO 6143 and ISO 17025, suitable for metrology and quality-control use.
Precision mixtures of propane in nitrogen or air are typically offered at concentrations from low parts-per-million up to percent levels, with the lower range chosen for trace-detector calibration and the higher range for flammability and LEL checks. Cylinders with passivated or treated interior surfaces help maintain stability of low concentrations over the shelf life shown on the certificate.
๐ญ Where Precision Propane Is Used
- โ๏ธ Analyser calibration โ process analysers on refineries and gas plants are spanned with propane in a nitrogen balance;
- ๐ฌ Emissions monitoring โ stack and ambient monitors are verified with traceable reference mixtures;
- ๐ฅ Fire and gas detection โ LEL sensors are bump-tested and calibrated with accurately known propane concentrations;
- ๐ Research and metrology โ calibration laboratories use gravimetric mixtures to establish measurement traceability.
๐ก Why Choose REAL GAZ
- โ Stated uncertainty โ each certificate reports the concentration together with its expanded uncertainty;
- ๐งช Gravimetric preparation โ components are weighed on calibrated balances rather than blended by pressure alone;
- ๐ฏ Stability data โ shelf-life guidance is based on the cylinder treatment and the mixture concentration;
- ๐ Custom concentrations โ special blends can be made to match the range of your analyser;
- ๐ Certificate of Analysis (CoA) โ supplied with every order.
๐ฌ Quality Control & Safety
- gravimetric blending on calibrated balances;
- analytical verification against reference standards;
- cylinder interior treatment for low-level stability;
- leak and pressure integrity checks before release.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
To protect accuracy, use a dedicated two-stage regulator with stainless-steel diaphragm, purge it several times before sampling and keep lines short and inert. Avoid using calibration cylinders below the minimum pressure shown on the certificate, since heavier components can deplete near the end of the contents. Store mixtures at stable temperatures, away from direct sun, and record the date of first use to keep within the stated shelf life.
