Ultra-Trace Oxygen Analysis in Semiconductor-Grade Gases
Sub-PPM Purity Verification for Semiconductor-Grade Specialty Gas Production — OMD-675
Producing semiconductor-grade specialty gases requires meeting stringent purity specifications, with allowable oxygen concentrations often specified in the low-ppb to sub-ppm range, depending on the gas and its intended application. Quality control at these levels requires highly sensitive oxygen analyzers capable of providing stable, repeatable measurements at ultra-trace concentrations.
The OMD-675 provides continuous ultra-trace oxygen measurement for compatible semiconductor-grade gases, helping producers detect oxygen contamination, monitor purification performance, and verify compliance with established oxygen purity specifications.

- Continuous Online Monitoring
Why Ultra-Trace Oxygen Analysis Matters
Semiconductor-grade gas customers depend on suppliers to consistently deliver products that meet stringent oxygen specifications, as even trace contamination can affect sensitive semiconductor manufacturing processes and potentially impact production yields. Continuous ultra-trace oxygen monitoring during gas production helps manufacturers detect purity deviations, evaluate purification performance, and maintain consistent product quality. When integrated with appropriate data recording and quality control systems, oxygen measurements also support documentation and verification of product specifications across production batches.
Where It's Used
- Purification system outlet monitoring — verifying purity after final gas treatment
- Production batch release — confirming each batch meets semiconductor-grade specification
- Blending and packaging quality control — verifying purity is maintained through final packaging
- Customer specification qualification testing — supporting new product or customer onboarding

Preguntas frecuentes
Oxygen specifications for semiconductor-grade gases vary depending on the gas type, purity grade, and intended manufacturing application. Many high-purity gases have oxygen limits in the sub-ppm range, while more demanding applications may specify concentrations in the low parts-per-billion (ppb) range. Gas producers should establish appropriate oxygen limits based on customer specifications, applicable industry standards, and process requirements. Ultra-trace oxygen analyzers such as the OMD-675 help verify compliance with these established limits.
The OMD-675 provides continuous ultra-trace oxygen measurements that can support quality control and batch release procedures for semiconductor-grade gases. When connected to a compatible data acquisition or recording system, oxygen concentration readings can be logged and associated with individual production batches. These records help manufacturers demonstrate that oxygen concentrations remained within established specifications and provide supporting data for certificates of analysis and customer quality documentation.
