Project Description

rapid N exceed®

Time for a change in protein analysis

Meet the most economic and innovative nitrogen/protein analyzer according to Dumas

The rapid N exceed® is designed to perform routine analyses of samples of food and feed with sizes of up to 1 g on a day to day basis. It represents a step to the next level of analytical technology by using a completely new method of reduction of nitric oxides and absorption of excess oxygen in the analysis gas. Due to a defined redox process (patent pending) the reduction agent is produced automatically during operation, enabling the reduction reactor to be used for several thousand samples. This makes the rapid N exceed a fast, safe and environmentally friendly analyzer.

Other benefits of the rapid N exceed® at a glance:

  • Long lifetime and 10-year guarantee
  • Few maintenance interventions and control samples
  • EAS REGAINER® and EAS REDUCTOR® technologies
