Helium-free, high performance N/protein analysis according to the Dumas principle

The use of helium as an inert carrier gas for nitrogen and protein analyzers is well established and until recently served as the only choice for Dumas analyzers.

This Technical Note describes the use of alternative carrier gases in our rapid N exceed® (carrier gas: carbon dioxide) and rapid MAX N exceed (carrier gas: argon) for high performance nitrogen and protein analysis.
