A new 'Gas Station' from Parker Hannifin provides both hydrogen gas and zero grade air for Flame Ionisation Detectors (FIDs) on gas chromatographs
The Process Air and Gas Filtration Division of Parker Hannifin has launched a new 'Gas Station' that provides both hydrogen gas and zero grade air for Flame Ionisation Detectors (FIDs) on Gas Chromatographs. Called FID 2500, the new model has been designed to produce up to 2.5 lpm of hydrocarbon-free air from an existing compressed air supply and 250 cc/min of fuel-grade hydrogen from deionised water. Most importantly, the FID 2500 allows users of gas cylinders to control and automate their gas supplies on site, eliminating the cost and inconvenience of sourcing zero air and hydrogen cylinder gas supplies from external suppliers.

In addition, the FID 2500 gas station can significantly enhance the sensitivity of chromatograph equipment, as zero air purity exceeds that of the cylinder gases with hydrocarbon content being less than 0.05 ppm.

Hydrogen gas is produced in the FID 2500 from deionised water using a Proton Exchange Membrane Cell, while the hydrogen generator uses the principle of electrolytic dissociation of water and hydrogen proton conduction through the membrane.

The hydrogen supply produces 90cc/min of 99.9995% pure hydrogen (UHP grade) at pressures of up to 4.1barg.

Zero air is produced by purifying on-site compressed air to a total hydrocarbon concentration of less than 0.1ppm, again measured as methane.

The zero air produces up to 1,000 cc/min of Zero Grade Air.

The FID 2500 is a complete system with innovative, highly reliable components engineered for easy installation, operation and long-term performance.

Furthermore, the new model features an ergonomic cabinet design, state-of-the-art catalysis module, visual operational status display, exceptional gas purity and automatic water filling for continuous operation.

In addition, the new system offers silent operation and requires minimal operator attention.

The Parker FID Gas Station has been designed and manufactured to meet some of the toughest laboratory standards in the world, including CSA, UL, CE and IEC 1010.

In addition, the unit meets NFPA and OSHA 1910.103 regulations, which govern the storage of hydrogen.
