Description
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 have 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.
