THE PROBLEM YOU'RE SOLVING

Trace Gas Contamination Destroys Process Integrity

Product Quality Failures

High level of moisture or oxygen in inert gas distribution systems cause oxidation, contamination, and batch failures in pharmaceutical API production and semiconductor processes.

Hidden Contamination

Moisture and oxygen contamination isn’t detectable without specialized analyzers. By the time production issues appear, you’ve already lost batches and revenue.

The Solution

Advanced trace gas analyzers from TigerOptics, Meeco, and Servomex detect moisture (dew point) and oxygen at PPB and PPM levels, verifying gas purity before contamination reaches your critical processes.

WHAT IS TRACE GAS ANALYSIS?

Ultra-Sensitive Detection for Gas Purity Verification

Trace gas analytical testing uses precision analyzers to measure moisture (dew point) and oxygen contamination in gas distribution systems. This testing verifies gas quality, and confirms gas system cleanliness meets pharmaceutical and semiconductor purity specifications.

Why Trace Gas Analysis Matters

Gas Purity Qualification and Verification

Confirms bulk gas and specialty gas systems maintained within specified purity levels. Detects trace moisture and oxygen that compromise system integrity

Post-Purge Confirmation

Documents successful removal of oxygen and moisture after system installation, modifications, or maintenance activities.

Contamination Troubleshooting

Identifies moisture or oxygen sources causing unexplained product quality issues, oxidation, or process failures.

INDUSTRIES & APPLICATIONS

Critical Testing Across High-Purity Industries

Essential gas purity verification where trace contamination causes failures

Semiconductor Manufacturing

Why Trace Gas Analysis Matters: Ultra-high purity gases require sub to low –PPB moisture and oxygen levels. Even trace contamination causes wafer defects, equipment corrosion, and yield losses.

Why Trace Gas Analysis Matters: Industrial gas suppliers and distribution networks must verify delivery gas purity to meet customer specifications and quality standards.

WHEN YOU NEED TRACE GAS ANALYSIS

Critical Testing Scenarios for Gas Purity Verification

Don’t wait for failures – schedule helium leak testing at these key milestones

New Facility Commissioning

Qualify all gas distribution systems before production startup. Document baseline purity levels for regulatory compliance if applicable.

Post-Purge Verification

Confirm successful removal of oxygen and moisture contaminants after system installation or modifications. Verify gas distribution systems meet purity specifications.

Routine Purity Monitoring

Periodic testing to ensure ongoing compliance with gas purity specifications. Detects gradual contamination before it affects production.

Post-Maintenance Testing

Re-verify gas purity following valve replacements, piping modifications, or equipment repairs. Ensure maintenance did not introduce contamination sources.

Contamination Investigations

Identify moisture or oxygen sources causing unexplained product quality issues, oxidation, or batch failures. Pinpoint contamination entry points.

Process Troubleshooting

Diagnose gas purity issues affecting process performance. Verify gas delivery systems meet equipment manufacturer specifications.

Emergency Response

24/7 rapid response for critical gas purity failures affecting production. Minimize downtime with immediate testing and contamination source identification (subject to availability, <3 hour mobilization).

FREQUENTLY ASKED QUESTIONS

Trace Gas Analytical Testing FAQs

What detection sensitivity can your equipment achieve?
Our TigerOptics HALO+, HALO3, and HALO analyzers detect moisture down to low PPB levels. Servomex oxygen analyzers measure from sub-PPM to low PPB levels. Actual sensitivity depends on gas type and analyzer model selected.
Duration varies by system contamination level. Clean, well-purged systems: 2-4 hours. Systems with trapped moisture or oxygen: 4-8 hours. We continue testing until readings stabilize at acceptable levels for a minimum 30 minutes.
Semiconductor high purity bulk and specialty gases: <10PPB for both moisture and oxygen. Industrial applications: per client specifications.
Yes. Gas distribution systems must be thoroughly purged to remove oxygen and moisture before analytical testing. This ensures testing measures system purity, not remaining installation contamination.
Yes, for some applications. We can sample from operational systems using proper connection points and safety protocols. Pre-test consultation determines the optimal sampling approach.
Testing frequency depends on industry requirements and system criticality. Semiconductor: after installation, modifications.
Testing frequency depends on industry requirements and system criticality. Semiconductor: after installation, modifications.
We first verify the analyzer function using gas purifiers. If the system is the contamination source, we identify likely causes (dead legs, leaks, purge gas contamination) and recommend corrective actions. We re-test after repairs or additional purging.
