Dumas Nitrogen Analyzer – Dual Carrier Gas

Helium has been the carrier gas for elemental analyzers for many years. After years of increasing prices and supply chain interruptions, obtaining Helium has become more and more difficult and expensive, especially in some countries.
The desire to replace Helium with a more easily accessible carrier gas has intensified and become reality. This is the reason why we have developed a N/protein analyzer able to use both Helium and its best alternative, Argon, without the need for replacing any part. This is NDA 702.
