Laboratory Nitrogen

Domnick Hunter nitrogen gas generators are the ideal source of nitrogen gas for the modern laboratory. They eliminate the need for costly, inconvenient, high pressure cylinders.

Nitrogen purities of 98% to 99.9995% are available to supply a number of applications, including GC, instrument purge, nebulising gas and blanketing.

Produce nitrogen gas from compressed air simply and cost effectively. Replace nitrogen gas cylinders for the following applications:

LCMS (single and multiple units)
ICP
ELSD
GC-carrier gas
GC-FID, NPD, ECD, AED
Solvent evaporation

Benefits

Designed to meet specific analytical instrument gas purity and flow requirements
Improved analytical performance - Production of a constant flow of gas improves the consistency of the analysis results and hence reproducibility /li>
Increased laboratory efficiency with a constant,guaranteed supply
Improved safety - No handling high-pressure gas cylinders or liquid dewars. Nitrogen production at controlled low pressures
Simple installation - Only one set up operation required for reliable service over time. Installation on or below a laboratory bench top, saving space in the laboratory
Economy - Quick return on investment - No gas cylinder rental bottles, no price inflation
Recommended by major instrument manufacturers
Combined N2 and Dry Air Generators - In addition to the stand alone nitrogen, zero N2 and dry air gas generators, domnick hunter also manufactures models that provide nitrogen and dry air from a single unit (models G6 and G7).
