The determination of the total protein content is an essential tool for quality control and protein declaration according to international labeling laws in the food & feed industry and research facilities. Since the protein content can directly correspond to product properties, highly precise, matrix-independent protein analyses are required in all application areas.

Our N/protein analyzers use the high-temperature combustion method according to Dumas, which has clear advantages over Kjeldahl regarding laboratory safety, sample throughput, labor time, amount of chemical waste and thus cost-per-analysis.

Available models

DKSH-Elementar-rapid-N-exceed
Technical Specifications
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

Faster, more precise, cost-saving, and eco-friendly. The rapid N exceed sets new standards in protein analysis according to the Dumas method. With our patent pending EAS REGAINER® technology, analysis costs are minimized drastically. At the same time, the number of samples that can be measured continuously multiplies. The new rapid N exceed stands for absolute precision and high detection sensitivity.

Key feature

  • Lowest cost per sample
  • Inexpensive CO2 as carrier gas
  • EAS REDUCTOR® for up to 2,000 samples
  • Fastest analysis (3-4 min.)
  • 300 measurements per day
  • Ease of use
DKSH-Elementar-Rapid-MAX-N-Exceed
Technical Specifications
Measuring method
High temperature combustion with 100% recovery and detection of the released nitrogen. 
For N/Protein “Dumas” analysis according to AOAC, DIN/ISO, EN and most relevant standards.
Easy sample handling
Direct weigh-in into re-usable crucibles (steel or ceramics) without any special pre-treatment. Suitable for solids or liquids up to several grams or milliliters.
Safe, fast, clean
The analysis takes only a few minutes. No aggressive or toxic chemicals required. Physical and chemical separation of water and and interfering gases.
Large concentration range

From 20 ppm to 100% or 500 mg absolute N content.
Few operational requirements

Less than 1 m laboratory working space, 1 electrical connection and 2 operating gases are sufficient for maintenance free long term operation. Operation with helium or argon carrier gas are standard.
Fully automatic

With integrated 90 sample changer, control through Windows® based operating software. 
Optional 21 CFR Part 11 compliant software.

Increased laboratory efficiency at significant lower price per sample. The rapid MAX N exceed is the first N / protein analyzer according to the Dumas method utilizing the highly successful EAS REGAINER® technology in combination with crucible-technology.  Designed for 24 / 7 unattended operation, the instrument addresses the needs of any highthroughput laboratory facing a wide range of sample types and weights. The rapid MAX N exceed stands for outstanding precision, sensitivity, and sample flexibility.

Key features

  • Ease of use
  • Simplified sample preparation
  • Lowest cost per sample
  • Argon as carrier gas (helium optional)
  • EAS REDUCTOR® for more than 1,000 samples
  • Fast analysis (5 min.)
  • 300 measurements per day
