In the gas industry – particularly in the production and distribution of industrial (Bulk Gas) and specialty gases – maintaining and continuously controlling gas quality with high and stable purity is essential to:

• Meet strict quality standards (e.g., ISO 8573, EN 589, ASTM D1946, etc.).
• Ensure safety in the production, storage, transportation, and utilization of gases.
• Optimize operational performance and minimize costs associated with quality-related issues.

The fundamental technical requirements include:

• Continuous, real-time monitoring of gas components and impurities.
• Early detection of compounds that may degrade purity or pose safety hazards.
• Analysis of compounds at trace levels (ppb, ppt) in a standard background gas environment.

To comprehensively address these requirements, Reecotech offers an automated gas chromatography (AutoGC) solution that applies modern analytical technology, tailored to specific gas sectors, as detailed below:

Quality Control in the Bulk Gas Industry – High Purity Analysis

In the industrial gas sector, ensuring gas purity reaches 99.99% (equivalent to Level 4.0) or higher is critical for maintaining production system performance and minimizing risks associated with impurities during processing, storage, and distribution.

To meet these demands, Reecotech proposes an analytical solution based on an automated gas chromatography system featuring the Chromatotec chromaTCD analyzer. This system is capable of continuous, real-time monitoring and precise analysis of primary gas components as well as unwanted impurities. Key features include:

• Monitoring gas quality at production, storage, and distribution facilities.
• Early detection of gas components that affect purity or compromise safety.
• Gas leak warning during transportation and distribution to ensure system integrity and minimize product loss.
• Support for output quality control to comply with stringent occupational safety and environmental regulations.

Quality Control in the Specialty Gas Industry

For niche industries such as the production of calibration gases or ultra-high purity background gases (e.g., Nitrogen, Helium), the detection and analysis of volatile organic compounds (VOCs) at trace levels is vital to ensuring product purity. This is especially important in applications such as analytical testing, research, chemical manufacturing, pharmaceuticals, electronics, and other high-tech sectors.

Reecotech provides the airmOzone PAMS VOC analysis system, which integrates modern analytical technology with the capability to:

• Simultaneously detect between 30 and 58 VOC compounds, including mercaptan, with a detection limit starting at 1 ppb.
• Optionally extend the trace VOC analysis range from 30 to 3000 ppt, suitable for applications requiring high sensitivity.
• Ensure high accuracy and repeatability in a standard background gas environment, meeting the most stringent quality control requirements for specialty gases.

The airmOzone PAMS solution optimizes the gas control process in the production of specialty gases, supporting laboratories and calibration gas manufacturing facilities in enhancing product reliability while ensuring long-term stability for systems requiring ultra-clean gas environments.
