RACK-FID-H2

This unit can provide both hydrogen gas and zero grade air to FID detectors on Gas Chromatographs.

Hydrogen gas is produced from deionised water using a Proton Exchange Membrane Technology. Zero air is produced by purifying compressed air sourced from the air network to a total hydrocarbon concentration of < 0.05 ppm (measured as methane). The RACK.FID.H2 generator combines the hydrogen serie ND-H2 and Zero air serie ZA generators in one unit.

The touch screen LCD interface provides simple and user friendly management of all functions on the unit.

Advantages

Improved chromatograph result
The reduction of hydrocarbons on zero air part, including, methane to < 0.05 ppm
decreases the background noise level and gives the baseline much better stability,
considerably increasing detector sensitivity and ensuring precise analytical results.
The use of hydrogen as a carrier gas allows lower temperature elution, thus extending the life of the chromatograph column.
Hydrogen as a carrier gas is faster and more sensitive than the more-expensive helium. Run time savings of 25% to 35% without a decline in resolution.

Increased laboratory efficiency
A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

Save money
The unit only requires connection to a suitable socket and to external source of compressed air for the zero air part. The investment can be paid back in less than one year

Improved safety
The very limited internal volume (less than 50 ml for H2) allows safe use of the gas generators where the use of cylinders is risky or prohibited. The application of tested safety technologies stops the unit in the event of leaks or malfunctions.

Simple installation
Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere.
