Gas generators

Gas generators for GC systems

High purity gases:

In chromatographic analysis, 3 different gases are predominantly required:

• Hydrogen and zero air as fuel gases in gas chromatography,
• Hydrogen and nitrogen as carrier gas
• Nitrogen in larger quantities in LCMS applications

Mode of operation:

Hydrogen is generated electrolytically in the gas generators (PEM technology) and subsequently treated in different ways (dried with a multi-dryer) depending on the application. Purities of 5.5-6.5 are achieved. Zero air is high purity air with a residual hydrocarbon content of up to less than 0.1ppm. Gas generators remove the organic impurities from your compressed air by means of a catalyst, thereby ensuring a constant air flow. Nitrogen is produced in ultra-high purity, in small quantities in the lower liter range with a purity of >99.9995%

Membrane technology is used to meet the requirements of the latest LCMS systems in terms of drying, wrapping, nebulization and collision of gases, even for larger quantities of nitrogen.

Advantages

• Constant pressure and continuous quality of the gases ensure higher stability and reproducibility of the results or chromatograms.
• The exchange of gas cylinders is no longer necessary and leads to less effort. This ensures a gas supply around the clock.
• High pressure gas cylinders are no longer required in the laboratory. This reduces the health and safety risk. The hydrogen generators shut down automatically in the event of a leak, which significantly reduces the risk of accidents.
• The purchase of a gas generator often pays for itself in less than 18 months.
• Cost reduction is achieved by eliminating the cost of providing, renting, storing and delivering gas
• Plug-and-play systems, even for critical applications
• A variety of models can be supplied with integrated oil-free compressors
• Units are compact and reliable with minimal operation and maintenance. Cost-effective maintenance kits, replacement diaphragms, filter kits are available for preventive maintenance or repairs after various hours of operation.
