NM Plus | Ultrapure hydrogen gas generators with up to 99.99996% purity (NM Plus Series)

Key Features

• Maintenance-free purification system generates carrier grade hydrogen gas to 99.99996% purity
• Flow rate options from 100 mL/min - 1350 mL/min (please see below)
• No pipeline or bottle changing requirements 
• No acid or alkaline solutions used in the hydrogen generation cycle
• Improved chromatographic results. Use of hydrogen as a carrier gas allows lower temperature elution and extended chromatograph column life.
• Advanced software control and safety alarm systems protect personnel. Limited internal volume (<50 mL) provides safer operating conditions compared to cylinders.
• Up to 32 units can be linked together for high volume output
• Automatic flow compensation
• Continuous operation for critical applications

Description

The NM Plus series of hydrogen gas generators produce carrier grade gas of 99.99996% purity for gas chromatography and other critical applications. The use of hydrogen as a carrier gas for gas chromatography provides more rapid separations than with other gases and with a minimum loss in chromatographic efficiency.

The NM Plus series produce hydrogen by forcing distilled or deionised water through an advanced Swiss-made titanium electrolytic cell. Electrolytic dissociation separates the water into its two main components: hydrogen ready for analytical use and oxygen that is released into the air. No acid or  alkaline solutions are used in the hydrogen generation cycle and the patented automatic drying system ensures the maximum level of hydrogen purity.

Safety is a major concern when using hydrogen so substituting the NM Plus for bottle or pipeline sources significantly increases the protection level. Advanced software control and safety alarm systems also protect personnel and a limited internal volume (<50 mL) provides safer operating conditions compared to gas cylinders.

The NM Plus series integrate systems for automatic flow compensation and continuous operation for critical applications. Up to 32 units can be linked together for facilities requiring high volume output.
