Importance of On-Site Gas Generation

On-demand gas generation addresses critical needs in modern analytical laboratories. It eliminates reliance on high-pressure cylinders, reduces recurring delivery costs, ensures consistent gas purity, and enhances safety by removing stored compressed gases from the workspace. This approach supports uninterrupted LC-MS, GC, ICP-MS, TOC analyzers, and other instrumentation, aligning with sustainability goals through lower carbon emissions and energy-efficient designs.

Objectives and Overview

This document presents Peak Scientific’s comprehensive portfolio of laboratory gas generators, spanning nitrogen, hydrogen, zero air, and specialty gases. It showcases distinct product lines—Genius, Solaris, Infinity, Precision, Specialist Solutions, i-FlowLab—and details their performance specifications, technological innovations, and service support. The objective is to guide laboratory managers and analysts in selecting optimal gas solutions to meet varied analytical demands.

Methodology and Instrumentation

Peak’s generators employ proven separation and purification technologies:

• Pressure Swing Adsorption (PSA) with customized carbon molecular sieves for ultra-high purity nitrogen.
• Membrane separation modules delivering up to 520 L/min of N₂ without integrated compressors.
• Proton Exchange Membrane (PEM) electrolysis for hydrogen generation at 99.9995–99.9999% purity.
• Multi-Stage Purification™ and Electronic Compressor Optimization™ (ECO) in high-flow Genius XE systems.
• Integrated dryers and catalyst chambers for hydrocarbon- and CO₂-free air in TOC and FT-IR applications.
• Modular air compressors conforming to ISO 8573-1:2010 Class 1.4.1 feed requirements.

Main Results and Discussion

Seven core ranges deliver tailored performance:
