rapid N exceed
50 years ago the rapid N saw the light of day for the first time!
Based on these experiences the rapid N exceed is the most economic and innovative nitrogen/protein analyzer according to Dumas. In day-to-day business it performs routine analyses of food or feed up to 1 g sample weight in your laboratory. The rapid N exceed represents the fast, safe and environmentally friendly alternative to the classical Kjeldahl method.
As the most innovative enterprise in the field of elemental analysis, Elementar takes this traditional analytical technology to a new level. This is made possible by a completely new method of reduction of nitric oxides and absorption of excess oxygen in the analysis gas. Due to a defined interaction of reduction and oxidation (patent applied for) used reduction agent will be automatically generated during operation. Thus, a reduction reactor (reductor) can be used for several thousand samples without change or maintenance.
At the same time, Elementar relies on proven technology for the newly developed rapid N exceed:
High temperature combustion
Dumas combustion method for N-Protein acc. to AOAC, DIN/ISO, EN and many international standards
Large weighing range
Up to 1 g sample weight (1g organic matter)
Concentration range
from ppm to 100% or 500 mg N abs.
Clean, safe, fast
The analysis only takes a few minutes, no aggressive or toxic chemicals are used, CO2 as intelligent carrier gas
Easy installation requirements
48 x 55 cm benchtop space, 1 power supply (230, 110, 100 V), and two gases are sufficient for maintenance free long time operation
Multipoint calibration
stable over months and matrix independent
Instrument control
with a standard PC for perfect results also for unknown or heavily variable sample matrices, 21 CFR Part 11 functionality available. Possibility for remote service due to full digitalization of the instrument electronics
