Precision Liquid CO₂ — tightly specified carbon dioxide for measurement work
Precision liquid CO₂ from REAL GAZ is carbon dioxide produced and certified to narrow tolerances, used where small deviations in purity or flow would affect results.
Typical grades reach 99.995 % with documented limits for oxygen, nitrogen, water and hydrocarbons.
Typical grades reach 99.995 % with documented limits for oxygen, nitrogen, water and hydrocarbons.
Preparation and testing follow ISO 17025 quality practice, with gas handling consistent with ISO 6142 and ISO 6143 for calibration mixtures, for analytical and industrial use.
🏭 Where Precision Liquid CO₂ Is Used
- ⚙️ Calibration gas blending — precision CO₂ is the base component when CO₂ calibration mixtures are prepared in nitrogen or air;
- 🔬 Emission monitoring — analysers measuring flue gas CO₂ are checked against reference mixtures;
- 🏥 Breath and gas analysis — research instruments sensitive to CO₂ are tested with consistent gas;
- 🚀 Electronics manufacturing — precision CO₂ is used in controlled resistivity water systems and in cooling of delicate parts.
📦 Precision Liquid CO₂: Grades, Cylinders & Handling
The value of a precision grade lies in its documentation as much as its purity. Each cylinder is traceable to its production batch, and the analysis report lists the measured level of key impurities rather than a general statement. The cylinder interior is cleaned and dried, and valves are fitted with seals suited to high purity service. For the most sensitive uses, a dedicated two-stage stainless regulator with a purge port allows air to be removed from the line before sampling. Do not mix the cylinder with regulators used for other gases. We keep records for each delivery, and returning cylinders with positive residual pressure helps preserve their cleanliness. Please tell us the acceptable impurity limits for your method before ordering.
💡 Why Choose REAL GAZ
- ✅ Narrow tolerance — analysis certificates specify impurity limits;
- 🧪 Stable cylinders — internal surfaces are cleaned to avoid contamination;
