Laboratory Nitrogen Generators

Domnick Hunter nitrogen gas generators eliminate the need for costly, inconvenient high pressure cylinders in the laboratory. Including an integral oil-free air compressor as standard, the generators deliver a continuous stream of 99.999% pure nitrogen gas with a residual oxygen content of <10ppm without the need for secondary purification.

Domnick Hunter nitrogen gas generators use a patented pressure swing adsorption (PSA) system, as
utilised in thousands of systems worldwide to remove oxygen, carbon dioxide and water from compressed air. The resulting stream of nitrogen gas is ideal for applications including GC carrier and make-up gas and instrument purging.

All Domnick Hunter nitrogen gas generators are designed and manufactured within a rigorous ISO9001 quality system. Built for total safety and reliability of operation, the generators are certified to CE and are fully year 2000 compliant.

Standard Features

• Integral oil-free air compressor
• Nitrogen purity 99.999%
• Digital hours run meter and service indicator
• Meets requirement of CE

Benefits and Savings

• Improved safety - Nitrogen produced at low pressure and ambient temperature removes the need for high pressure cylinders or liquid dewars
• 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
• Improved economy - 99.999% pure nitrogen gas produced as standard. No need for costly downstream secondary filtration
• Security of supply - Integral oil-free air compressor guarantees continuous gas supply, independent of in-house compressed air supply
• 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

Laboratory Hydrogen Generators

Domnick Hunter NITROX hydrogen gas generators produce a continuous supply of ultra-high purity hydrogen gas from laboratory grade deionised water, ideal for GC carrier and fuel gas applications.

NITROX Laboratory Hydrogen Generators details

domnick hunter NITROX hydrogen gas generators provide a safe and economic alternative to high pressure gas cylinders in the laboratory. Using the principle of electrolysis, the generators produce a continuous supply of ultra-high purity hydrogen gas from a supply of laboratory grade deionised water, ideal for GC carrier and fuel gas applications.

Laboratory Zero Air Generators

Domnick Hunter NITROX zero air generators are the ideal source of fuel gas for GC-FID, producing ultra-high purity zero air from a house compressed air supply, with methane levels of less than 0.1ppm.

NITROX Laboratory Zero Air Generators details

Domnick Hunter NITROX zero air generators produce ultra-high purity zero air from a house compressed air supply, removing methane levels to less than 0.1ppm. This ensures consistently flat GC baselines and reduces cleaning requirements of FIDs. Producing zero air from an existing air supply eliminates the need for expensive air cylinders in the laboratory and payback can be typically less than six months

CO2 Removal Purifiers

Domnick Hunter NITROX CO2-removal purifiers are ideal for FT-IR purge, NMR, laser purging and rheometer supply, removing CO2 from compressed air to less than 1ppm and providing a dewpoint of less than –70oC.

NITROX CO2 Removal Purifiers details

Domnick Hunter NITROX CO2-removal purifiers are ideal for FT-IR purge, NMR, laser purging and rheometer supply. The generators purify an existing compressed air supply to provide a continuous supply of instrument quality air with CO2 content of less than 0.1ppm and dewpoint of less than –70oC. With payback of one year, the generators provide a real economic alternative to high pressure cylinder supply.

Pure Air Generators

Domnick Hunter NITROX pure air generators totally clean a supply of compressed air. Dewpoint of –40oC is produced as standard, with particle removal to less than 0.01ppm and non-methane hydrocarbons of less than 0.01ppm.

NITROX Pure Air Generators details

A supply of compressed air is an essential utility for any modern laboratory. Compressed air contains water, dirt and oil, which can damage sensitive pneumatic instruments and affect the performance and life of analytical instruments. Domnick Hunter NITROX pure air generators prevent the occurrence of such problems by removing such contaminants from an existing compressed air supply. Dewpoint of –40oC is produced as standard, with particle removal to less than 0.01ppm and non-methane hydrocarbons of less that 0.01ppm.
