N2 Tower Plus Nitrogen Generators
The new N2-Tower Plus series of nitrogen generator produce high purity nitrogen for all major applications in analytical laboratories. Nitrogen generators eliminate the problems associated with the handling of high pressure gas tanks and reduce the cost of high purity nitrogen immediately.
The N2-TOWER Plus series of nitrogen generators use air from a separate compressor and remove the oxygen to less than 10ppm (hydrocarbons to <0.1ppm is optional). The guaranteed flow rates of pure nitrogen are 500 ml/min, 750 ml/min, 1300 ml/min or 4000 ml/min depending on the generator module.
SPECIFICATIONS
* LED-display for status
* Maintenance control light
* Alarms for catalyst duration, catalyst temperature, and pressure
* Simple filter removal without the need to open the instrument
APPLICATIONS
N2-TOWER Plus series nitrogen generators are ideal for the method development and routine analysis by GC, GC-HS, ICP, HPLC-ELSD.
* GC carrier gas and make-up gas
* ICP / HPLC-ELSD
* GC / FTIR
* Incubators
* TGA-DSC
BENEFITS
The constant high purity of the nitrogen provides stable conditions for analytical systems and guarantees highly reproducible results. The purchase price for the nitrogen generator is generally recovered in about one year, since there is no longer the extra cost involved in handling, transporting, storing, and purchasing high pressure gas tanks. The installation is very simple and quick, as is the routine maintenance.
OPERATING PRINCIPLE
Compressed air from an outside source (not included) passes through a charcoal filter for pre-cleaning before the oxygen is removed by the double column pressure swing adsorption (PSA) system. One of the PSA columns is active while the second one is regenerated. The removed gases, like oxygen, are released back to the atmosphere.
With an optional catalyst, other trace impurities such as hydrocarbons and CO are removed to levels <0.1 ppm. An additional filter is installed to remove particulates down to 0.5 microns. For the complete removal of all hydrocarbons, an optional catalytic oven is available. This will guarantee trouble-free operation of FID detectors in GC.

N2-Whisper Nitrogen Generators
The Whisper nitrogen generator has been developed to meet the flow, purity and pressure requirements of LCMS applications. It can also be used for the evaporation of solvents in samples being analyzed. The simple, high efficiency membrane technology separates nitrogen from the other components of a compressed air supply. The low pressure drop (1 bar) means that the Whisper can share a dry, oil-free compressed air source already in the lab.
Benefits
BETTER RESULTS FROM ANALYTICAL INSTRUMENTS
The constant purity of the nitrogen improves system stability and ensures reproducible results.
BETTER LAB EFFICIENCY
Gas bottles are insufficient to ensure good lab productivity.
COST SAVINGS
The equipment cost is normally recovered in less than a year. In addition, no pipeline is required to carry gas from the storeroom to the lab.
IMPROVED SAFETY
Nitrogen produced at low pressure and room temperature eliminates the risks associated with high pressure gas bottles and the handling of liquid nitrogen.
…AND SIMPLE INSTALLATION
The Whisper nitrogen generator is very easy to install in the lab. No power connection is required. It can sit on the bench top or be wall-mounted to save bench space!
OPERATING PRINICPLE
When the compressed air is forced through the hollow fiber membrane, components like oxygen, carbon dioxide, water vapor, and traces of rare gases pass through the membrance. Nitrogen diffuses through the membrane slower than the other components, so it remains behind, ready for use.
