Bespoke LC/MS Nitrogen Generators Facilitate Better Analysis
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 1,100 ml/min of ultra high purity hydrogen, 99.9999%. These make an ideal choice for both carrier gas and fuel gas on all GC applications.

Modern LC/MS instruments employ large flows of nitrogen for nebulisation and drying in the interface. However, the gas demands of different instruments vary extensively depending on the design of the interface, with some instruments even employing multiple gases. Therefore, one standard gas supply may not necessarily meet all the demands of the instrument and therefore deliver an optimum performance to the user. Parker domnick hunter offers the widest range of LC/MS Nitrogen Generators which most effectively match instrument gas requirements, compared to any other LC/MS generator manufacture.
Bespoke models have been fully researched, designed and approved for use with Agilent, Waters, AB Sciex, Thermo and Bruker LC/MS instruments to offer optimum performance to the user. All Parker domnick hunter Nitrogen Generators employ robust and totally regenerative carbon molecular sieve technology to guarantee optimum performance, durability and lifetime cost effectiveness. A range of tailored, preventative maintenance contracts are also available via a dedicated global aftermarket network which offers complete peace of mind.

Clean Dry Zero Air for GC-FID
Together, we can deliver optimum, cost-effective and safe GC analysis.
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.
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.
