Nitrogen/Protein Analyzer - rapid N exceed®

The rapid N saw the light of day for the very first time 50 years ago.

Based on these experiences the rapid N exceed is considered to be the most economic and groundbreaking nitrogen/protein analyzer according to Dumas. In day-to-day business it carries out routine analyzes of food or feed up to 1 g sample weight in a laboratory. The rapid N exceed represents the safe, fast and environmentally friendly alternative to the classical Kjeldahl method.

Elementar, as the most advanced enterprise in the field of elemental analysis, Elementar takes this traditional analytical technology to a new level. This is brought about by a totally new method of reduction of nitric oxides and absorption of surplus oxygen in the analysis gas. Due to a distinct interaction of reduction and oxidation (patent applied for) used reduction agent will be automatically produced during operation. Thus, a reduction reactor (reductor) can be employed for several thousand samples without maintenance or change.

Elementar, at the same time, relies on established technology for the newly developed rapid N exceed:

  • The rapid N exceed never takes a break: it works 24/7 – 365 days a year
  • The post-combustion ensures exact results, independent of any sample matrix
  • CO2 as carrier gas saves the finite resource helium and guarantees stable prices and constant availability
  • The fastest protein analysis with analysis times of less than four minutes and greatest sample throughput in this instrument class
