February 24, 2014, Haverhill, MA – The Filtration and Separation Division of Parker Hannifin Corporation, the global leader in motion and control technologies, has introduced a new line of Zero Nitrogen Generators designed to transform standard compressed air into a safe, regulated supply of 99.9995% pure nitrogen with <0.1 ppm hydrocarbons.
Nitrogen is produced by utilizing a combination of filtration and pressure swing adsorption (PSA) technologies. Standard compressed air is filtered by high efficiency coalescing filters to remove all contaminants down to 0.01 micron. The air then passes through two columns filled with proprietary carbon molecular sieve (CMS) which adsorb oxygen (O2) and carbon dioxide (CO2), moisture, and hydrocarbons. These are desorbed to atmosphere during the pressure swing cycle leaving a supply of ultra-pure nitrogen.
For ultra-sensitive applications that use electron capture detectors (ECD), units include a heated catalyst module and are specifically designed to replace P5 argon/methane mixtures as well as ultra-high purity nitrogen.
The generators include an economy (ECO) mode which allows the generator to switch into standby mode when there is no demand from the downstream instrument. During this period, the integral compressor stops which reduces the number of running hours and extends the life of the compressor. This significantly reduces the ongoing running costs for replacement compressors, servicing, and downtime. Additionally, the design incorporates advanced noise reduction via the installation and mounting of the compressor and the placement of sound reduction insulation.
Typical applications include gas chromatography (GC) makeup gas and carrier gas, ECD, differential scanning calorimeter (DSC), and any other type of analytical instrumentation requiring a small flow of ultra-high purity zero nitrogen.
