High Purity CO₂ Distributor — trace-controlled carbon dioxide for exacting users
REAL GAZ acts as a High Purity CO₂ Distributor, delivering carbon dioxide with a guaranteed minimum purity and tightly limited trace impurities.
Typical grades range from 99.99% (4.0) to 99.999% (5.0), with moisture, oxygen and total hydrocarbons reported on the analysis.
Typical grades range from 99.99% (4.0) to 99.999% (5.0), with moisture, oxygen and total hydrocarbons reported on the analysis.
Analytical work is traceable under ISO 17025 principles, calibration mixtures are prepared against ISO 6142, and purity is evaluated in line with ISO 14175 where applicable.
Purity claims mean little without evidence. Every high purity lot handled by REAL GAZ is accompanied by an analysis listing the CO₂ content together with water, oxygen, nitrogen, carbon monoxide and total hydrocarbons. When a method demands tighter limits than our standard grades, we discuss the requirement with the producer and confirm what is realistically available before you commit.
🏭 Where High Purity CO₂ Is Used
- ⚙️ Supercritical fluid extraction — high purity CO₂ extracts flavours, oils and botanicals without solvent residues;
- 🔬 Supercritical chromatography — SFC mobile phases need consistent CO₂ to keep baselines stable;
- 🏥 Semiconductor processing — cleaning and cryogenic aerosol applications depend on low particulate and moisture levels;
- 🚀 Cell culture incubators — laboratories control atmosphere in incubators with precisely regulated CO₂.
💡 Why Choose REAL GAZ
- ✅ Impurity limits — moisture, oxygen, nitrogen and hydrocarbons are controlled to published maxima;
- 🧪 Dedicated equipment — filling lines and cylinders are reserved to avoid cross-contamination;
- 🎯 Cylinder preparation — internal surfaces are evacuated and conditioned before each fill;
- 🔒 Distribution reach — a single supplier for several laboratory sites reduces ordering complexity;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- trace moisture measurement with chilled mirror or similar analysers;
- gas chromatographic purity checks;
- vacuum and purge cycles on every cylinder;
- pressure integrity tests on stainless-steel or brass valves.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Keeping Purity at the Point of Use
- Choose stainless-steel diaphragm regulators and electropolished tubing so that trace moisture is not reintroduced downstream;
- Purge lines with the gas before analysis and leak-test every joint, since a small ingress of air can outweigh the cylinder specification;
- Avoid elastomers that absorb CO₂ and release it slowly, and replace them with metal-seated or fluoropolymer components;
- Store cylinders at stable room temperature and order in line with the shelf life stated on the certificate.
