Ultra High Purity Zero Nitrogen Generators

The Parker domnick hunter zero nitrogen  generators employ robust, field proven technology to produce ultra high purity nitrogen for GC makeup and carrier gas applications. An integral heated platinum catalyst ensures carrier grade nitrogen free from organic impurities to <0.1ppm.

The generators provide a continuous stream of ultra high purity nitrogen from a single ’plug & play’ unit. Models are available with and without an integral oil free compressor, are extremely quiet in operation and are fully approved for use by major instrumentation manufacturers.

Innovative design features include economy mode as standard which extends compressor life and significantly reduces on going running costs.
