Clean Dry Zero Air for GC-FID
The Safe Hydrogen Carrier Gas Solution for GC
The benefits of switching GC carrier gas from helium to hydrogen, such as faster analysis and improved resolution, have long been understood. Financial motives to drive change have also gained recent momentum due to the continual escalation in the market price of helium.
Major concerns over heightened safety risks associated with the use of hydrogen gas remain at the fore and cylinder based hydrogen supplies offer little opportunity to significantly avoid or improve safety levels in the laboratory.
Conversely, the Parker domnick hunter H-MD range of Hydrogen Generators with highly sophisticated software control and alarm capability present the GC user with the opportunity to reap all the benefits offered by hydrogen, whilst overcoming the safety concerns.
H-MD generators are available in four models to deliver flows of 160, 250, 500 and 1,100ml/min of ultra high purity hydrogen, 99.9999%. These make an ideal choice for both carrier gas and fuel gas on all GC applications.
The Parker domnick hunter Zero Air Generators use a combination of high level filtration and catalytic technologies to produce a flow of clean, dry air with ultra low residual hydrocarbon levels of less than 0.1ppm.
The modular generator design allows it to be used individually or coupled to any one of the Parker domnick hunter Hydrogen Generators to form an all-in-one FID Gas Station solution for GC combustion detector applications.
Available in seven flow rates from 1 to 30 lpm, the generators can be used to supply single or multiple installations.

New Range of Ultra High Purity (UHP) Nitrogen Generators From Parker domnick hunter
A safer alternative to hazardous and expensive nitrogen cylinders is now available from a new range of UHP nitrogen generators from Parker domnick hunter, a world leader in separation and filtration technologies.
Generating your own nitrogen on-site will remove the risks associated with the logistics and handling of high pressure
gas cylinders and their onerous administrative requirements. All models are available with the option of an integral compressor for a complete ‘plug and play’ solution, or can simply be connected to the facility instrument air supply.
Incorporated into the innovative design from the outset, advanced sound reduction technology allows these generators to be installed directly into the laboratory.
During periods of no nitrogen demand, a full economy feature automatically switches the generator to an energy saving ‘standby mode’. This not only saves the unnecessary waste of energy, but also considerably prolongs compressor life to maximise uptime and provide even further on-going cost benefits.
With 21 models in the new range, there is a flow, pressure and purity option to meet virtually any analytical or laboratory application. UHP generators (99.9995%) are available with hydrocarbon removal to 0.1ppm making them ideal for all purity sensitive applications, including Gas Chromatography (GC) with Electron Capture Detectors (ECD). Applications include GC (both fuel and carrier gas requirements), Total Organic Carbon, Nuclear Magnetic Resonance, Circular Dichroism, Inductive Coupled Plasma (OES & MS), Evaporative Light Scattering Detectors and solvent evaporators.

Together, we can convert your GC from Helium to hydrogen carrier gas.
The benefits of using hydrogen as a GC carrier gas are proven; faster analysis, greater resolution and longer column life. In addition, with the price of non-renewable helium increasing at a rapid rate, hydrogen is now also considered to be the cost-effective option. Nevertheless, major concerns with safety continue to prevail.
The Parker domnick hunter H-MD hydrogen gas generator however, offers intelligent control and safety alarms to counter such risks whilst facilitating optimum GC instrument performance and reduced bottom-line gas costs.
