Experis Ultra High Purity gases

Experis Ultra High Purity Gases

Importance of Topic
Analytical instrumentation and process control require gases with minimal impurities to ensure accurate measurements and instrument longevity. Achieving consistent purity reduces background noise and prevents column degradation in chromatography.

Objectives and Overview
This summary outlines the range of Experis UHP gases supplied by Air Products, highlighting available grades, purity levels, cylinder formats, quality assurance protocols, and the proprietary BIP purification technology that delivers parts per billion impurity control.

Used Instrumentation

• High precision gas regulators and manifolds engineered for UHP delivery
• Extensive leak testing and ISO 9001 certified quality management
• BIP purification cylinders with in situ filters to remove oxygen, moisture, hydrocarbons, and other trace contaminants

Methodology and Purification Technology
The Experis portfolio includes common gases such as argon, nitrogen, helium, hydrogen, oxygen, carbon dioxide, synthetic air, and acetylene, each produced in multiple grades ranging from Premier to Pharma. BIP technology employs a unique filter system inside cylinders to achieve ultra-low impurity concentrations, often below 10 ppb for O2 and H2O, and below 20 ppb for total hydrocarbons. Pharma grades comply with European Pharmacopoeia and GMP Part II standards, providing full traceability and certification.

Key Specifications and Discussion

• Premier grades offer high purity in the ppm range for general analytical use
• BIP and BIP Plus grades reduce key impurities to the ppb level for demanding chromatographic and semiconductor applications
• Oxygen, nitrogen, and argon BIP grades achieve overall purities above 99.9992%
• Custom cylinder sizes from 2 L up to 18-cylinder packs accommodate diverse usage scenarios

Benefits and Practical Applications

• Enhanced chromatographic column life and reduced dew points
• Lower baseline noise in detectors and improved analytical precision
• Compliance with pharmaceutical and semiconductor manufacturing requirements
• Peace of mind from certified batch or individual cylinder analysis

Future Trends and Opportunities
Advances may include further expansion of BIP technology to new gases, integration with smart gas delivery systems for real-time purity monitoring, smaller format cylinders for lab-on-a-chip applications, and increased automation in gas management and analytics.

Conclusion
The Experis UHP gas range offers a comprehensive solution for high-precision analytical and industrial applications. With rigorous quality assurance and innovative purification methods, users gain reliable performance and regulatory compliance across multiple sectors.
