Back to Basics: How to Choose the Right Gas Generator for Your Laboratory Needs – A Guide from LNI Swissgas
Choosing the right gas generator for your laboratory is a crucial decision that impacts the efficiency, safety, and accuracy of your analytical processes.
At LNI Swissgas, we understand the complexity of this choice and are here to guide you through the process. As the market leader, we offer the widest range of gas generators and accessories, providing comprehensive lab solutions from hydrogen to zero air generators, rack models, benches, and more. You can contact us or visit one of our worldwide experience and training centers for personalized assistance.
Meanwhile, here’s a simple step-by-step guide to help you choose the right gas generator for your laboratory needs:
Step 1: Understand your application
Start from your instruments, not from the generator.
Consider the following:
Check the various requirements of the instrument (type of gas, purity, pressure etc). Different instruments such as gas chromatographs, mass spectrometers, and atomic absorption spectrometers have varying gas purity and pressure requirements.
Identify your gas requirements:
- Hydrogen: Often used as a carrier gas in gas chromatography (GC) and for flame ionization detectors (FID).
- Zero Air: Used to calibrate and zero instruments such as gas analyzers.
- Nitrogen: Commonly used in liquid chromatography-mass spectrometry (LC-MS), gas chromatography (GC), and as a purging gas.
Ensure the gas generator you choose can deliver the required purity levels for your specific applications. Different applications require different levels of gas purity.
For instance:
- Ultra-High Purity (UHP) Gases: Essential for sensitive analytical techniques such as GC-MS.
- High Purity Gases: Suitable for most general laboratory applications.
- Standard Purity Gases: Adequate for less critical tasks.
Consider the flow rate and pressure requirements of your laboratory instruments. Different generators have varying capacities:
- Flow Rate: Measured in liters per minute (LPM), ensure the generator can supply a consistent flow that matches or exceeds the demand of your instruments.
- Pressure: Ensure the generator can provide the necessary pressure for optimal instrument performance.
Step 2: Consider Safety and Compliance
Safety is a fundamental element of any gas generation system.
Modern generators are designed to improve laboratory safety by reducing the risks associated with high-pressure cylinders and uncontrolled gas supplies.
Always ensure the selected system complies with relevant safety and quality standards, and includes integrated protection and monitoring features.
A safe gas supply is the foundation of a reliable laboratory.
Step 3: Assess Installation and Space Constraints
A gas generator must fit your laboratory environment.
Evaluate available space, installation feasibility, and integration into existing layouts. Footprint, noise level, heat management, and accessibility all influence daily usability.
- Benches: LNI provide customizable bench solutions to integrate gas generators seamlessly into your laboratory setup. Check here our range of benches.
Step 4: Check Maintenance and Operating Costs
A gas generator is a long-term investment.
Beyond the initial cost, consider energy consumption, consumables, maintenance needs, and service support. These factors determine the real cost of ownership.
Energy-efficient systems and structured service programs help reduce downtime, operating expenses, and long-term risk.
Efficiency is not only economic — it is operational.
Step 5: Utilize LNI Swissgas experience and training centers and seek expert advice
In case of specific needs or uncertainties, take advantage of LNI Swissgas’s various Experience and Training Centers located throughout the globe. These centers provide opportunities to:
- Test Products: See and test LNI Swissgas products in action to ensure they meet your laboratory’s needs.
- Receive Training: Gain in-depth knowledge and training on the operation and maintenance of gas generators.
If you’re unsure about which gas generator to choose, don’t hesitate to seek expert advice. LNI Swissgas provides comprehensive customer support and can assist you in selecting the most suitable generator for your specific needs.
Step 6 – Service, support, and partnership
Technology alone is not enough.
A true partner provides application support, system customization, certified calibration, responsive service, and long-term continuity.
Because the performance of a generator is not defined only by how it is built — but by how it is supported.
