Hydrogen is used in chromatography both as a carrier gas and as a fuel for flame ionization detectors (FID) or flame photometric detectors (FPD). It is either delivered in classical gas cylinders or produced on site. On-site production ensures a continuous supply and allows for small total hydrogen volumes in the lab.
Where the use of cylinder hydrogen is restricted, the HiQ® hydrogen laboratory gas generator is safe to operate, due to its small contained volume (< 40 ml). In case of an internal error, for example, the unit is put on standby by an auto-shut-off procedure. Selectable, multiple alarms alert to unwanted shifts in operating conditions such as low water level, poor water quality, low pressure (leak) and power supply conditions.
Hydrogen - HiQ® laboratory gas generators
The HiQ Hydrogen laboratory gas generators are the economical alternative to high pressure gas cylinders in the laboratories. Purities of up to 99.9999% are available and the generators offer silent operation at pressures up to 10.5 barg (155 PSI).
The generators require just demineralised or distilled water to produce Hydrogen. No caustic solutions are needed and no cell maintenance is required at all. Hydrogen from the model HiQ H2 FID is the ideal fuel gas for the GC-FID’s or as reactor gas for other types of detectors in gas chromatography. The model HiQ H2 CARRIER has been designed to replace Helium or Nitrogen as carrier gas.
Hydrogen from the HiQ H2 CARRIER generator offers important advantages over Helium and Nitrogen in terms of speed analysis, sensitivity and resolution. Other Hydrogen applications include total hydrocarbon analyzers, sulphur analyzers and air-pollution monitoring systems.
The HiQ H2 FID and the HiQ H2 CARRIER hydrogen generators are “No Maintenance” systems which require little bench space. In addition, HiQ H2 CARRIER is optionally available with cascading and remote control capabilities. These unique and exclusive features open a wide range of new applications.
The HiQ Hydrogen laboratory gas generators are very compact, safe, ergonomic and cost effective. In addition to their high safety (production of Hydrogen only when required), the generators have been designed to meet highest quality and reliability standards.
