Laboratory Ar-N₂ Mix For Purchase — small-lot mixtures prepared for analysis
A Laboratory Ar-N₂ Mix for purchase from REAL GAZ is supplied in compact cylinders designed for benchtop and instrument use. Laboratories typically need low consumption with high certainty, so volumes and certificates are matched to that profile.
Concentrations can be requested in ppm, mol% or vol%.
Concentrations can be requested in ppm, mol% or vol%.
Documentation references ISO 6142 and ISO 17025, and uncertainty statements follow ISO 6143 methods for laboratory and industrial QA teams.
🏭 Where Laboratory Argon–Nitrogen Mixes Are Used
- 🔬 Instrument calibration — detector response is set against certified argon–nitrogen references;
- 🧪 Method validation — a known mixture supports linearity and repeatability studies;
- 🌡️ Environmental monitoring — reference gases check ambient and stack analysers;
- 📚 Teaching laboratories — students use safe inert mixtures for practical sessions.

📦 Grades, Cylinders & Handling
- 📌 Sizes — 1 to 10 litre cylinders are commonly used in laboratories;
- 📌 Fittings — confirm the valve outlet before ordering;
- 📌 Use — do not use below the minimum residual pressure given on the certificate;
- 📌 Disposal — return empty cylinders through the agreed route.
🧭 Using a Reference Mixture Correctly
A certified mixture is only as good as the way it is used. Connect it with clean, leak-tight stainless steel or suitable polymer lines, purge the regulator several times before opening the cylinder fully, and allow flow to stabilise before taking a reading. Do not exhaust the cylinder completely; stop at the residual pressure given on the certificate, because the last portion may be affected by wall effects. Keep the cylinder at a stable temperature, since large changes can influence regulator performance. Record the cylinder number and certificate date in your calibration log so the traceability chain remains complete for audits and accreditation reviews. Store spare cylinders away from windows and radiators, and rotate stock so older certificates are used first. If your accreditation body expects a particular uncertainty format, tell us when ordering, so that the certificate presents the values in the layout your assessors prefer.
