Rapid N Exceed

Time to rethink protein analysis

The Rapid N is a nitrogen/protein analyzer according to Dumas. In day-to-day business it performs routine analyses of food or feed up to 1g 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: 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 highest sample throughput in this instrument class.
The post-combustion guarantees exact results, independent of any sample matrix.
The rapid N exceed never takes a break: it operates 24/7 – 365 days a year.



  • 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 (1 g organic matter)
  • Concentration range
    from ppm to 100% or 500 mg N abs.
  • Multipoint calibration
    stable over months and matrix independent
  • 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
  • Automated sample analysis
    with integrated sample feeder for 60 samples (80 or 120 sample positions optional) and PC control under Windows®
  • 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
