Ultra-Trace Oxygen Analysis in Semiconductor-Grade Gases

Sub-PPM Purity Verification for Semiconductor-Grade Specialty Gas Production โ€” OMD-675

Producing semiconductor-grade specialty gases requires meeting some of the tightest purity specifications in industrial gas production, with oxygen limits often specified in the low-ppb to sub-ppm range. Production quality control at this level requires analyzers capable of dependable, drift-resistant measurement at the very limits of trace detection.

The OMD-675 supports semiconductor-grade gas producers with continuous, highly sensitive oxygen monitoring, verifying product purity meets the demanding specifications this market requires.

Why Ultra-Trace Oxygen Analysis Matters

Semiconductor-grade gas customers depend on suppliers to consistently deliver product within extremely tight oxygen specifications, since even minor deviations can affect fab yield. Continuous ultra-trace oxygen monitoring throughout production gives gas producers the process control and documentation needed to reliably meet these specifications batch after batch.

Where It's Used

  • Purification system outlet monitoring โ€” verifying purity after final gas treatment
  • Production batch release โ€” confirming each batch meets semiconductor-grade specification
  • Blending and packaging quality control โ€” verifying purity is maintained through final packaging
  • Customer specification qualification testing โ€” supporting new product or customer onboarding

Recommended Analyzer

The OMD-675 is built for the sensitivity semiconductor-grade gas production demands, delivering stable measurement down to sub-ppm and low-ppb levels depending on configuration.

Deployed at key production and quality control checkpoints, the OMD-675 provides the continuous, documented purity data that semiconductor-grade gas customers require.

Trace oxygen measurement provides a direct indication of oxygen contamination or crossover into the hydrogen stream. Trending the oxygen concentration can help operators identify changes in electrolyser or purification system performance.

A common measurement point is the hydrogen product stream downstream of the electrolyser stack. Additional measurement points may be used before or after drying and purification equipment depending on the process design and monitoring objectives.

Alarm and control limits should be determined based on the electrolyser manufacturer’s specifications, process conditions, applicable standards, and the facility’s safety requirements rather than using a universal oxygen alarm value.
