Hydrogen Generators for Gas Chromatography

Palladium Membrane

Hydrogen on Demand, up to 300 ml/min

Ultra high purity hydrogen generators from Parker Balston are designed as hazard-free alternatives to high-pressure hydrogen cylinders. Deionised water and an electrical supply is all that is required to generate hydrogen for weeks of continuous operation.
Automatic feed-water is available as standard for remote installations or where minimal operator attention is required.

With an output capacity of up to 300 ml/min, one generator can supply 99.99999% pure fuel gas for up to 7 FID’s or several GC’s with carrier gas.

 

 

 

Product Features:

• Produces a continuous supply of 99.99999% pure hydrogen gas at up to 4.1 bar
• Designed to run 24 hours a day
• Certified for laboratory use by CSA, UL, and CE marked
• Eliminate dangerous hydrogen cylinders from the laboratory
• Simple low cost annual maintenance
• Ideal for fuel and carrier gasrequirements

 

Certified Safety

Parker Balston hydrogen generators utilise an exclusive palladium membrane to produce hydrogen on demand. A built in pressure transducer monitors the down stream requirements. This ensures the hydrogen generator produces only enough gas for the application keeping internal storage to an absolute minimum.

A sophisticated control system connected to a liquid crystal display, continuously monitors the vital operating parameters to ensure a safe and consistent performance.

That’s why Parker Balston hydrogen generators meet the strict safety guidelines to be certified for CE, CSA and UL approval.

 

Proven Technology

Parker Balston’s exclusive Palladium Membrane is proven in thousands of GC installations worldwide.
Maintenance requires only a few minutes per year - no inconvenient extended downtime. Simply change the electrolyte every 12 months.
Hydrogen gas is produced by electrolytic dissociation of water. The resultant hydrogen stream then passes through a palladium membrane to ensure ultra high purity.

Only hydrogen and its isotopes can penetrate the palladium membrane; therefore, the purity of the output gas is consistently 99.99999+%

PEM (Proton Exchange Membrane)

Hydrogen on Demand,up to 510 ml/min

Ultra high purity hydrogen generators from Parker Balston are designed as hazard-free alternatives to high-pressure hydrogen cylinders. Deionised water and an electrical supply is all that is required to generate hydrogen for weeks of continuous operation.

Optional automatic feed-water is available for remote installations or where minimal operator attention is required. With an output capacity of up to 510 ml/min, one generator can supply 99.9999% pure fuel gas for up to 12 FID’s or several GC’s with carrier gas. The compact design allows the generators to be installed directly in the laboratory eliminating the requirement for long hydrogen lines.

 

Product Features:

• Produces a continuous supply of 99.9999% pure hydrogen gas at up to 6.9 bar
• Designed to run 24 hours a day
• Compact, reliable and minimal maintenance
• Eliminate dangerous hydrogen cylinders from the laboratory
• 2 years standard warranty
• Ideal for fuel and carrier gas requirements

 

Certified Safety
Parker Balston hydrogen generators utilise an exclusive Proton Exchange Membrane to produce hydrogen on demand. A built in sensing circuit shuts the generator down if a hydrogen leak is detected and an eight-stage explosion protection system ensures the highest level of operator safety.

A sophisticated control system connected to a liquid crystal display, continuously monitors the vital operating parameters to ensure a safe and consistent performance.

That’s why Parker Balston hydrogen generators meet the strict safety guidelines to be certified for CE, CSA and UL approval.

 

Proven Technology
Parker Balston’s exclusive Proton Exchange Membrane is proven in thousands of GC installations worldwide. Maintenance requires only a few moments per year – no inconvenient extended downtime.

Simply change the deioniser cartridge every 6 months and the desiccant cartridge as required.
If contaminated water or low water levels are detected, the system activates a warning light and shuts off the generator. A small pump and environmental filters also ensure that the electrolytic cell is supplied continuously with high quality water - avoiding damage to the electrolytic membrane.

Parker Balston’s hydrogen generators are the most reliable hydrogen generators on the market today.

Nitrogen Generators for Gas Chromatography

 

 

Nitrogen on Demand, up to 2,000 ml/min

The Parker Balston Ultra High Purity (UHP) Nitrogen Generators are engineered to transform standard compressed air in to a safe regulated supply of 99.9999% pure nitrogen.

Typical applications include GC make up gas and carrier gas, including ECD (Electron Capture Detector), solvent evaporation, DSC (Differential Scanning Calorimeter) and virtually any analytical instrument that requires a small flow of ultra high puirty nitrogen.

 

 

Product Features:

• Produces a continuous supply of high purity nitrogen 99.9999% for GC applications
• Ideal for make-up and carrier gas applications including ECD
• Eliminate dangerous nitrogen cylinders from the laboratory
• Ideal for TOC applications including combustion, UV persulate and wet oxydation sampling techniques
• Low maintenance, minimal operation attention
• Designed to run 24 hours a day

 

Nitrogen is produced by utilising a combination of filtration and pressure swing adsorption (PSA) technology. 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 carbon molecular sieve (CMS) which adsorb O2, 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 such as ECD, units are also available with the addition of a heated catalyst module to ensure hydrocarbons are removed to < 0.1 ppm.

Zero Air Generators for Gas Chromatography

The Parker Balston Zero Air Generator can produce up to 30,000 ml/min of high purity zero grade air. Compressed air is pre filtered down to 0.01 micron and then purified using a state-of-art combined heated catalyst module.

There are no moving parts and no noise, making the generator extremely reliable and ideal to install in the laboratory. Simple and quick to install, the Zero Air Generator requires minimal maintenance just once a year.

The resultant air is free of total hydrocarbons (THC) to < 0.05ppm making it ideal for all FID applications. The low levels guarantee a low signal to noise ratio, ensuring a flat constant base line with no peaks or fluctuations.

 

 

Product Features:

• Ultra high purity air for GC FID applications
• Payback period typically less than one year
• Silent operation and minimal operator attention required
• Eliminate inconvenient and potentially dangerous air cylinders from the laboratory
• Models available to service up to 75 FID’s
• Increases the accuracy

 

 

The chromatograms compare baselines produced by a Parker Balston Zero Air Generator and cylinder air.
The baseline produced by the Parker Balston Generator is very flat, with no fluctuations or peaks, in comparison with the chromatogram of the cylinder air supply, which has many peaks ranging from 0.25 ppm to -0.25 ppm
