How important is the supply of nitrogen to your business? For many companies, a reliable supply of nitrogen gas is essential. Parker domnick hunter understands the key role nitrogen can play and the fundamental need for a reliable and secure supply.
For over 40 years Parker domnick hunter has been a world leader in filtration, purification and separation technologies in a diverse range of industries, Parker domnick hunter is universally known for developing high quality products, technical innovation and partnerships with customers.
Nitrogen Generators
Parker domnick hunter LC/MS nitrogen generators are specifically designed to meet the gas flow, purity and pressure requirements of the latest generation of LC/MS instruments.
Increase the efficiency of your laboratory by replacing nitrogen gas cylinders for applications such as:
- GC make-up/carrier gas
- ICP
- ELSD
- XRD
- Solvent evaporation
- NMR
- CD
Hydrogen Generators For GC Fuel Gas Applications
Replacing hydrogen cylinders with a Parker domnick hunter laboratory hydrogen generator instantly reduces health and safety issues by signaling an end to high pressure flammable gas storage, cylinder manual handling and gas line
management.
Simple and easy to maintain desiccant cartridge based technology in the 20, 40 and 60H generators provides a fieldproven, robust solution for applications that do not require the highest purity grade of hydrogen.
Eliminate high pressure hydrogen cylinders from the laboratory by generating your own continuous source of analytical grade hydrogen. Parker domnick hunter offers two ranges of laboratory hydrogen generators. The ‘H’ range is ideal for supplying hydrogen fuel gas to all known combustion detectors used routinely in GC and THA. The ‘H-MD’ range provides a higher purity grade of hydrogen and can be used for GC and GC/MS carrier gas applications
as well as ICP-MS reaction gas.
Both ranges deliver flow rates ranging from 160 ml/min to 500 ml/min. Hydrogen is generated on demand from no more than de-ionized water and electricity. The gas is stored only at low pressure, and the volume of stored gas is minimal. These features, combined with a unique generator monitoring and alarm system provide unrivalled levels of end user safety, reliability, performance and cost of ownership.
Using hydrogen as a GC carrier gas significantly increases analysis speed and separation efficiency compared to helium. Gas costs and downtime are also significantly reduced due to the change from a cylinder-based supply. Fully integrated, fully regenerative micro dryer technology in the H-MD range provides the optimum combination of reliability, performance and cost of ownership for high purity applications such as GC carrier gas and ICP reaction gas.
Nitrogen Generators For Higher Flowrates
Parker domnick hunter also manufactures comprehensive ranges of MIDIGAS and MAXIGAS nitrogen generators. These provide flowrates typically ranging from 10 l/min to 882 l/min at purities from 10ppm to 3% oxygen content. Even higher flowrate generators can be provided if required. The larger flow rates afforded by the Parker domnick hunter MAXIGAS range means the generators are ideally suited for use as the basis of centralised laboratory nitrogen supply systems capable of supplying multiple instruments and applications. System modularity allows the capacity of the system to be easily increased as laboratory operations expand. For more detailed information about this range, please contact Parker domnick hunter.
Zero Nitrogen, Nitrogen and Air and Dry Air Generators
In addition to the stand-alone nitrogen generators, Parker domnick hunter also manufactures zero nitrogen, dry air and combined nitrogen and dry air generators for the following applications:
Zero Air Generators
Parker domnick hunter zero air generators produce a continuous flow of clean, dry air with an ultra low residual methane content of less than 0.05 ppm from an existing compressed air supply. An interchangeable top panel allows for direct mounting of a Parker domnick hunter UHP hydrogen generator. The generators can be used to supply zero air to the following applications:
- GC-FID, FPD, NPD
- LC/MS
- THA
- Gas sensing
