When testing for volatiles at ppb or even sub ppb-level it is of outmost importance to run the detectors like ion mobility spectrometers with an operating gas of highest purity in order to avoid backround contamination and by that assure best performance of the instrumentation. The N2-Generator of G.A.S. was particularly developed for the autonomous, mobile and by that flexible use of analytical devices where zero air is no option e.g. testing of flammable gases. Using the N2-Generator makes cylinder management redundant and allows analyzers to be operated continuously (24/7) with nitrogen of highest grade (5.0) generated from enriched ambient air.
The N2-Generator has a compact design of 19” housing including the integrated customized compressor. An on-/off menu same a standard connectors enable a convenient/'plug-and-play' coupling of the machine to any device.
Since 2020, the system can also be ordered in a 'tower version' for laboratory use. The cleaning and compressor units are separated from each other and the latter is equipped with a soundproof box for noise reduction.
The applied pressure-swing technology enables auto-regeneration of the O2-retarding filters while the integrated molecular sieves assure that ambient air of even elevated humidity can be handled. Thus exchange of filters (depending on concentrations of impurities, chemical compounds and humidity) are typically in the range of beyond 6 month.
By this both N2-Generator versions are ideal and complementary tools for any G.A.S. instrumentation that merge convenience with value for money in the field same as for the lab use.
