Parker Domnick Hunter Ultra High Purity Nitrogen Generators laboratory gas generators for mass spectrometery lc/ms, gc/ms, ms/ms - from krss

Ultra High Purity Nitrogen Generators

The Parker domnick hunter nitrogen gas generators employ robust, field proven technology to produce ultra high purity nitrogen for critical life science, chemical analysis and spectroscopy applications. Flow rates range from 0.55 L/min to 3 L/min, with purities >99.9995%.

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 an 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.
