Precision Liquid Oxygen — tightly controlled oxygen for exacting processes
Precision liquid oxygen describes liquid oxygen supplied with defined purity, controlled impurities and consistent delivery conditions so that sensitive processes behave predictably. REAL GAZ works with customers to define what precision means for their application.
For some users it is about trace hydrocarbons; for others it is about pressure stability or documentation; we cover each of these.

Control practices align with ISO 17025, ISO 9001, EN 13458, ISO 21029 and EIGA Doc 13, suitable for device manufacturing, electronics and calibration laboratories.
Quality planning for tight specifications begins with sampling. We agree where samples are drawn, the cylinder or container used, how it is purged and which analytical method is applied. Typical reporting covers oxygen content, moisture, total hydrocarbons and particles, with uncertainty values where the method supports them. Records are archived by lot number so that any later question about a process batch can be answered with data rather than assumption. Where calibration laboratories need extra confidence, we can provide parallel samples for independent analysis in their own accredited facility and compare the results with our data.
🏭 Where Precision Liquid Oxygen Is Used
- ⚙️ Device manufacturing — oxygen is used in plasma treatment of polymer components and in the preparation of process chambers;
- 🔬 Thin-film deposition — reactive sputtering of oxide films demands oxygen of stable purity to repeat film thickness and quality;
- 🏥 Calibration blending — vaporised oxygen is the base component for calibration mixtures that need accurate oxygen fractions;
- 🚀 Metrology — reference laboratories use oxygen of known quality to verify analysers and paramagnetic sensors.
