Dürr nitrogen generator Chromalytic HF30N/ HF60N/ HF30N-MG/ HF60N-MG
The versatile models in this nitrogen generator series are specially designed for laboratories and research institutions where mass spectrometers need to be supplied with high reliability. Thanks to integrated nitrogen accumulators and proven separation membranes, they impress with their efficiency and durability. Anyone looking for a compact yet powerful solution benefits from reduced operating costs and minimal space requirements. Similarly designed devices, such as the NitroFlow Basic, also offer flexible application options, allowing laboratory operators to consider different options depending on their needs.
Performance features and areas of application
This series has been specially developed for continuous operation in state-of-the-art LC-MS systems. The functionality extends to all typical analytical applications, particularly in pharmaceutical research, food control laboratories and chemical analyses. Protein research, veterinary drug analysis and pesticide determination can also be easily covered. Compared to conventional methods, which often work with separate individual devices, the nitrogen generator significantly reduces maintenance requirements. Similarly designed systems such as the HF20N generator show that a modular design can meet all common requirements in the laboratory environment.
For optimum results, the device relies on high-quality filter stages and excellent membrane separation. As nitrogen separation and drying take place in a single step, it is possible to generate both nitrogen and dry air at the same time. The latter is particularly interesting for laboratories that require compressed air as a source and exhaust gas flow for their devices - such as those from Sciex or Bruker. The compact dimensions allow installation directly under or on the workbench, providing additional space in confined areas.
Important technical data
- Volume flow N₂ at 0 bar: 32 l/min (HF30N) or 64 l/min (HF60N)
- Purity: up to 99.5%
- Nominal pressure: 7 bar
- Typical dew point: -40 °C (HF30N/HF60N) or -20 °C (MG versions)
- Noise level: approx. 49 dB(A) at 1 m
- Nominal power: 0.8 kW
- Protection class: IP54
- Weight: 45 kg
In addition, the MG version supplies up to 100 l/min of air if required, which is particularly advantageous if there is a higher demand for dry air. Both versions can be supplied via an existing laboratory air system or a separate compressed air source. Protection class IP54 and operating class S1 document suitability for locations where continuous operation is required and ambient conditions between +5 °C and +35 °C occur.
The generators are ideal for identifying pharmaceuticals, pesticides and veterinary medicines, for example as part of a routine check. They are also useful for detecting molecular ions in research, for example in protein analysis or in basic research into metabolic processes. Food technology also benefits when measuring acrylamides in samples, for example.
FAQs
How often is maintenance necessary?
The maintenance intervals are comparatively long. A regular filter change and a check of the membrane are the main tasks, so that maintenance costs remain low.
Can several units be operated in parallel?
Yes, the generators have a modular design. Connecting several units allows additional redundancy or a higher delivery capacity to be covered.
What air quality is required for operation?
Clean, filtered compressed air is a prerequisite. In a typical laboratory air system or with a separate, external compressed air source, suitable filter stages are usually already in place.
Is CE certification available
Dürr Technik attaches great importance to high-quality components and safe manufacturing processes. More detailed information on CE or other certifications can be found in the official manufacturer documentation.
How quickly is the required amount of nitrogen available?
As the device runs in continuous operation, the nitrogen is available almost immediately. Thanks to the integrated storage tank, a constant and rapid supply is ensured.
Conclusion
This innovative device platform offers a particularly reliable solution for all laboratories that need to generate nitrogen for LC-MS applications or other analytical procedures on site. The ability to provide nitrogen and dried air in one system reduces the need for additional components. Together with the proven, maintenance-friendly design, the system is a decisive factor for efficient and economical laboratory processes.
