Gas Generators - For PerkinElmer Instruments

Importance of the Topic

In modern analytical laboratories, consistent and high-quality gas supply is critical for the reliable operation of liquid chromatography–mass spectrometry (LC-MS) and gas chromatography (GC) systems. Dedicated on-site gas generation reduces dependency on gas cylinders, enhances safety, and lowers operational costs while ensuring stable gas purity and flow.

Aims and Overview

This document outlines the collaboration between Peak Scientific and PerkinElmer to develop dedicated nitrogen and air generators tailored to PerkinElmer’s QSight LC-MS platforms. It presents the objectives behind the partnership, an overview of the customized product range, and the service model designed to support global laboratory operations.

Methodology and Instrumentation

Peak’s gas generation solutions employ two core technologies: membrane separation and advanced compressor-based systems combined with multi-stage drying filtration. These approaches deliver instrument-grade gas with minimal contaminants. Key generator models include:

• Genius XE QSD: A dual-output generator with integrated compressor supplying nitrogen (up to 16 L/min at 80 psi) and air (up to 67 L/min at 110 psi) for QSight Dual Source LC-MS.
• Genius 1025: Compressor-based membrane generator producing LC-MS grade nitrogen (up to 15 L/min at 80 psi) and dry air (up to 35 L/min at 110 psi) for QSight Triple Quad systems.
• Infinity 1046: Compressor-free design requiring clean lab air, delivering up to 20 L/min nitrogen and 70 L/min dry air silently and with low maintenance.
• Precision Nitrogen 600 series: Compact generators offering 99.9995 % purity nitrogen for carrier, make-up, reference gas, and sample preparation, available in trace and standard models.

Main Results and Discussion

Customized Peak generators precisely match PerkinElmer instrument requirements for pressure, flow, and purity. Validation by PerkinElmer confirms compatibility and performance. Manufacturing excellence, ISO 9001 certification, and rigorous quality control ensure reliable long-term operation. A global network of certified Field Service Engineers provides rapid on-site warranty support and preventative maintenance.

Benefits and Practical Applications

Peak’s dedicated gas generators offer several advantages:

• Independence from gas cylinders reduces supply chain risks and storage issues.
• Factory-preset flows and pressures streamline installation and daily operation.
• Low noise, heat, and energy consumption improve laboratory environment and sustainability.
• Comprehensive on-site warranty and service plans safeguard instrument uptime and performance.

Future Trends and Possibilities

Ongoing innovations in compressor design, electronic compressor optimisation, and digital diagnostics will enhance energy efficiency and predictive maintenance. Integration with laboratory information management systems (LIMS) and remote monitoring platforms will enable proactive servicing and data-driven performance optimization. As multi-omics and high-throughput applications evolve, demand for customizable gas purity and flow profiles will grow, driving further specialization of gas generation technology.

Conclusion

The Peak Scientific–PerkinElmer partnership delivers precision-engineered gas solutions that align with the stringent demands of modern LC-MS workflows. Combining advanced generator technology, tailored engineering, and global support ensures seamless, cost-effective gas supply, empowering laboratories to maintain peak analytical performance.
