(U)HP Series - Pioneering ultra-high purity nitrogen solutions for high-end applications
Pure and precise - developed for your analyses

- Designed for laboratories with a nitrogen requirement of up to 2 l/min
- Uses advanced PSA technology and achieves a nitrogen purity of 99.9995%
- Integrated two-stage coalescence: particle filtration and activated carbon filter for maximum purity
- Optional function: removal of hydrocarbons to less than 0.05 ppm
 
Hydrocarbon-free nitrogen is important for improving gas quality, especially in GC analysis. The optional hydrocarbon separator ensures highly pure output gas (99.9999% or 6.0 grade) with a residual moisture content of <0.05 ppm, ensuring reliable analysis. Impurities in gases can significantly affect the quality of GC results, leading to background noise, altered peak shapes, false positives, or poorer consumption efficiency.
 
The optional hydrocarbon separator actively counteracts these issues.
Nitrogen generators with PSA technology for your analytical applications
With the (U)HP1 and (U)HP2 versions, Dürr Technik expands its range of nitrogen generators for analytical applications requiring ultra-high purity gas. These models are ideal for laboratories with a central compressed air supply or a source of clean high-pressure air (e.g., a Dürr Technik compressor station). Thanks to their compact dimensions, Chromalytic nitrogen generators can be installed under the workbench to save space.
 
PSA technology is the ideal method for high purity levels and is used in the (U)HP1 and (U)HP2 models. Efficient nitrogen separation ensures a reduced total air requirement and guarantees the production of high-purity nitrogen. Pressure swing adsorption (PSA) separates nitrogen molecules from oxygen molecules by adsorbing the oxygen from the compressed air flow. Lower real operating costs and a reduced carbon footprint make Chromalytic nitrogen generators the ideal solution for your laboratory.
