Gas Generators For SCIEX Systems

Significance of the Topic

On-site generation of high-purity gases such as nitrogen, hydrogen and zero-air is vital for modern analytical laboratories. Consistent gas quality underpins the performance of LC-MS and GC systems, ensuring reliable sensitivity, reproducibility and low operational costs. Integration of gas production with instrument workflows reduces downtime, removes cylinder handling risks and supports stringent QA/QC standards.

Objectives and Overview

This document examines the collaboration between Peak Scientific and SCIEX to deliver tailored gas generator solutions. It outlines the joint development process, product series matching specific SCIEX platforms, and the global support infrastructure designed to maintain uninterrupted laboratory operations.

Methodology and Instrumentation

• Compressor-based technology (Genius Series) integrates air compressors within the generator, delivering on-demand nitrogen and dry air without external supply.
• Membrane-based systems (Infinity & Solaris Series) separate nitrogen from compressed air supplied by the laboratory, offering silent, low-maintenance operation.
• Modular workstations (MS Bench SCI) combine integrated gas generation or noise-abatement enclosures for vacuum pumps beneath a chemical-resistant bench surface.

Main Results and Discussion

Peak Scientific offers three core product lines optimized for various SCIEX instruments:

• Genius Series: Single-unit compressors delivering up to 26 L/min of nitrogen and up to 25 L/min of dry air at pressures up to 6.9 bar.
• Genius AB-3G and NM-3G: Three-gas systems with redundant compressor capacity, advanced alarms and self-diagnostics for continuous operation in demanding applications.
• Infinity Series: Compressor-free membrane generators available in flow ranges from 19 to 104 L/min, silent operation and minimal maintenance.
• Solaris XE: Stackable membrane modules offering variable flow (up to 35 L/min), adjustable pressure (to 8 bar) and purity (up to 99.5%).
• MS Bench SCI: Workstations with integrated gas generation (G variant) or noise-reducing vacuum pump enclosures, fully certified for SCIEX benchtop systems.

These systems have been validated across the full spectrum of SCIEX LC-MS instruments, ensuring precise curtain, source and exhaust gas feeds. The robust design incorporates insulated compressor compartments, advanced service indicators and a comprehensive on-site warranty to minimize laboratory disruptions.

Benefits and Practical Applications

• Continuous, on-demand supply of analytical-grade gases without cylinder logistics.
• Optimized footprint through integrated bench solutions and stackable modules.
• Lower total cost of ownership via reduced consumable expenditure and energy-efficient designs.
• Global field service network offering rapid response, preventive maintenance plans and end-to-end support.

Future Trends and Opportunities

• Integration of digital monitoring and remote diagnostics to further reduce downtime and improve predictive maintenance.
• Expansion of modular generator platforms to support emerging MS techniques and higher-throughput workflows.
• Advancements in membrane materials and compressor efficiencies for even lower energy consumption.
• Sustainable laboratory design driven by reduced cylinder waste and on-site production powered by renewable energy sources.

Conclusion

The collaboration between Peak Scientific and SCIEX has yielded a comprehensive portfolio of gas generators that are precisely matched to LC-MS and GC instrument requirements. Through combined R&D excellence, tailored product development and a global service network, laboratories benefit from reliable, cost-effective and low-footprint gas solutions. Continuous innovation and digital integration will drive future improvements in performance and sustainability.
