Dürr ultra-high purity nitrogen generator (U)HP A with compressor
The Dürr ultra-high purity nitrogen generator (U)HP A with compressor offers a particularly pure nitrogen supply for demanding laboratory applications. With its advanced PSA technology and optional hydrocarbon separation, the system is ideal for sensitive analytical methods. High-purity nitrogen plays a decisive role in GC applications in particular, as impurities can significantly distort the measurement results. Similar features to the [HP2A from DÜRR TECHNIK] also offer reliable purity and flow performance, so that every user can choose the right variant.
Powerful and efficient solution for precise analysis
This system combines state-of-the-art pressure swing adsorption (PSA) with two-stage coalescence filtration, consisting of a particle filter and an activated carbon filter. This achieves a nitrogen purity of up to 99.9995 %, which is particularly critical for gas chromatography or mass spectrometry applications. If required, an optional hydrocarbon separator can be used to reduce the HC content to below 0.05 ppm. This ultra-high purity minimizes disturbing effects such as background noise or imprecise peak shapes and achieves a more reliable result quality.
Thanks to its compact dimensions, the device can be accommodated under the laboratory workbench to save space. At the same time, efficient nitrogen generation lowers the need for compressed air, which reduces operating costs and the carbon footprint. These advantages make the model the first choice for laboratories where very constant purity and a stable nitrogen supply are required. Similar concepts for capacity expansion or redundancy are possible with the [UHP1A from DÜRR TECHNIK] if higher requirements exist.
The most important technical features at a glance:
- Purity of the nitrogen: up to 99.9995 %
- Optional HC content: 0.05 ppm (only for UHP A)
- Nominal output: 1 kW
- Nominal pressure: 7 bar
- Typical dew point: -40 °C
- Noise level: approx. 55 dB(A)
- Weight: approx. 45 kg
In addition, the robust design with high-quality components ensures durability and reliability in everyday laboratory use. The IP54 protection class ensures safe operation, even when the device is used in demanding environments. Thanks to the ease of maintenance, filter media can be easily replaced, minimizing downtime and costs.
Application examples
- Gas chromatography (GC/GC-MS): High-purity nitrogen with minimal hydrocarbon residues ensures consistent baselines, clear peaks and precise quantification for analytical questions.
- Atomic absorption spectroscopy (AAS): The high purity avoids interference in the signals and ensures reproducible measurements over a long period of time.
- Elemental analyzers: In areas of protein analysis or when determining elemental compositions (e.g. C, H, N, S), a continuous and reliable supply of nitrogen at constant pressure is essential.
FAQs
How often do filter components need to be replaced?
The maintenance intervals depend on the application and the operating hours. As a rule, replacement takes place at fixed intervals, with a standardized mechanism making replacement particularly easy.
Can the device supply several devices at the same time?
Yes, the system can supply multiple gas chromatography lines or other instruments thanks to the available flow rate of up to 2 l/min and the option to interconnect multiple units.
What role does the optional hydrocarbon separator play?
It reduces the hydrocarbon content to below 0.05 ppm and thus prevents interference in highly sensitive analyses, for example in trace analysis using GC-MS.
Is an additional compressor necessary?
The model is already equipped with an integrated compressor. An external compressed air source is only required if you want to increase the throughput or create redundant solutions.
Conclusion
This PSA-based generator system with optional hydrocarbon separator covers the demand for high-purity nitrogen up to 2 l/min and is therefore suitable for a wide range of laboratory applications. The compact design and robust technology reduce long-term costs and ensure uncomplicated installation. Anyone who values maximum purity, low operating costs and flexible application options will find this nitrogen generator a convincing solution.
