Gas Generators for Agilent Instruments Series 1

Tower High Purity Hydrogen / Zero Air in one box

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 the exclusive 100% titanium Proton Exchange Membrane (PEM) technology for H2, which provides a very high reliability and new longer life. 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 T.FID.MB.H2 generator combines the hydrogen serie MB.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.

Applications :

  • GC-FID • GC-FPD • GC-NPD
  • Mud logging application for oil industry

BENEFITS AND SAVINGS

  • 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.

OPERATING PRINCIPLE

Hydrogen is produced using distilled or deionized water from hydrolysis, through a polymer membrane.

Electrolytic dissociation separates the water into its two main components: hydrogen ready for analytical use, and oxygen that is released into the air. No acid nor alkaline solutions are used in the hydrogen generation cycle.

Zero Air part use three steps to transform ambient air into analytical grade air.

Step 1 : Pre-filtration.

The external oil-free compressor delivers air through a high efficiency filter that traps any particles that may damage the system. The filter has an automatic purge and traps oil, water and any other particles larger than 5 microns in size.

Step 2 : HC and CO trapping

The air leaving the filter enters a high-temperature platinum catalyser, which through oxidation eliminates hydrocarbon molecules down to < 0.05 ppm.

Step 3 : Final filtration

A high-efficiency filter is used to prevent any kind of particles from entering the instrument.
