DESCRIPTION
SPECIFICATION

A versatile Dumas Protein/Nitrogen Analyzer, able to perform precise nitrogen analysis and protein determination using either Helium or Argon as carrier gas. Ideal for markets where Helium is scarce, it offers high throughput and precision. NDA 702 is a new conception nitrogen/protein Dumas analyzer, ensuring excellent performance on both solid and liquid samples and equipped with the TEMS™ technology. NDA 702 gives the possibility to choose between Helium or Argon, without the need for replacing any part. After years of increasing prices and supply chain interruptions, obtaining Helium, the conventional carrier gas, 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.
