Installing a Nitrogen Generator
for Sample Preparation

1. Cost Efficiency: Unlike nitrogen cylinders, which require frequent replacement and associated logistics, a nitrogen generator provides a continuous supply of gas, reducing long-term costs. Try our nitrogen generator payback calculator now!

2. Safety: Nitrogen generators eliminate the risks associated with storing and handling high-pressure gas cylinders.

3. Consistency and Purity: Generators can produce nitrogen at consistent purity levels, crucial for sensitive analytical procedures.

4. Environmental Impact: Generators reduce the carbon footprint by minimizing transportation and the use of disposable cylinders.

Assessing Laboratory Requirements 

Before selecting a nitrogen generator, evaluate the specific needs of your laboratory:

- Flow Rate: Determine the volume of nitrogen required per minute (L/min) based on your equipment and application demands.

- Purity Level: Identify the purity required for your applications (e.g., 99.99% for gas chromatography).

- Pressure: Assess the pressure needs of your instruments to ensure compatibility with the generator’s output.

Choosing the Right Type of Nitrogen Generator 

Several types of nitrogen generators are available, each suited for different laboratory applications:

- Membrane Generators: Ideal for general applications with moderate purity requirements.

- Pressure Swing Adsorption (PSA) Generators: Provide higher purity nitrogen, suitable for critical applications like mass spectrometry.

- Cryogenic Generators: Typically used for ultra-high purity requirements.

Site Preparation

Proper site preparation is crucial for the successful installation and operation of a nitrogen generator:

- Space and Ventilation: Ensure adequate space for the generator, allowing for proper ventilation and easy access for maintenance.

- Electrical Requirements: Verify that the electrical supply meets the generator’s specifications, including voltage and current.

- Environmental Conditions: Maintain an environment with stable temperature and humidity levels, as extreme conditions can affect performance.

Integration with Laboratory Systems

Seamlessly integrating the nitrogen generator with existing laboratory systems involves:

- Piping and Connections: Use appropriate materials and fittings to connect the generator to your instruments, ensuring leak-free and secure connections.

- Monitoring and Control: Implement monitoring systems to track gas flow, purity, and pressure, helping to maintain optimal performance and detect issues early.

- Backup Systems: Consider installing backup nitrogen sources or generators to ensure continuous operation during maintenance or emergencies.

Unpacking and Positioning 

Carefully unpack the nitrogen generator and position it according to the site preparation plan. Ensure that it is stable and accessible for maintenance.

Electrical and Mechanical Setup 

- Electrical Connection: Connect the generator to the power supply, following the manufacturer’s instructions to avoid electrical hazards.

- Mechanical Connection: Attach the generator to the laboratory's gas distribution system using compatible fittings and piping. Use a leak detection solution to check for leaks.

Initial Startup and Calibration 

Follow these steps for the initial startup and calibration: 

- System Purge: Purge the system to remove any contaminants or residual gases.

- Calibration: Calibrate the generator according to the manufacturer’s guidelines to ensure accurate nitrogen production.

- Testing: Run a series of tests to verify the output flow rate, purity, and pressure, adjusting settings as necessary.

Maintenance and Troubleshooting

Regular maintenance is essential to keep the nitrogen generator operating efficiently:

- Scheduled Maintenance: Follow the manufacturer's maintenance schedule, including filter replacements and system checks.

- Performance Monitoring: Continuously monitor key parameters, such as output pressure and nitrogen purity,  to detect performance deviations early.

- Troubleshooting: Develop a troubleshooting protocol for common issues, such as fluctuations in purity or flow rate. To ensure that your troubleshooting protocol works for your lab, review the manufacturers recommendations for your specific generator. 

Safety Considerations 

Nitrogen generators are safer than traditional cylinders, however safety guidelines should always be followed. Adhere to: 

- Emergency Procedures: Establish and train staff on emergency shutdown procedures.

- Ventilation: Ensure adequate adequate ventilation to prevent nitrogen buildup, which can displace oxygen and create a hazard.

- Routine Inspections: Conduct regular safety inspections to identify and mitigate potential risks.

Installing a nitrogen generator in your laboratory can enhance operational efficiency, reduce costs, and improve safety. By carefully assessing your needs, choosing the right generator, and following a systematic installation process, you can ensure a successful integration of this critical equipment into your laboratory workflow.

For laboratories looking to stay at the forefront of sample preparation technology, a nitrogen generator is an investment that promises both immediate and long-term benefits.
