Nitrogen and Protein Analyzer
What is the rapid N exceed PLUS?
The Elementar rapid N exceed PLUS is a compact nitrogen and protein analyzer designed for fast, reliable determination of nitrogen content in a wide range of sample matrices. Using the Dumas combustion method, the instrument enables laboratories to determine nitrogen and calculate protein content without the acid digestion required by the Kjeldahl method.
With analysis times of approximately 3–4 minutes per sample, sample weights up to 1.5 g and a cost-efficient CO₂ carrier gas, the rapid N exceed PLUS combines analytical performance with low operating costs.
The analyzer is suitable for routine quality control and laboratory analysis in the food, feed, agricultural, environmental and materials sectors.
Low operating costs with EAS REGAINER technology
The rapid N exceed PLUS is designed to minimize the cost per analysis while maintaining reliable analytical performance.
Instead of relying on helium as a carrier gas, the instrument uses CO₂, providing a cost-efficient alternative for routine nitrogen and protein determination.
Elementar’s EAS REGAINER® technology extends consumable operating life and reduces replacement frequency. Combined with simplified maintenance and reduced calibration requirements, this helps laboratories minimize operating costs and instrument downtime.
Reliable nitrogen determination across different sample matrices
The rapid N exceed PLUS combines optimized sample introduction with controlled combustion to support accurate nitrogen measurements across different sample types.
Its matrix-independent calibration approach reduces the need for frequent recalibration or matrix-specific standards. The instrument also provides detection capabilities in the low ppm range, making it suitable for applications involving low nitrogen concentrations.
The system accommodates solid and liquid samples, with preparation procedures adapted to the sample matrix.
Supported sample types
The rapid N exceed PLUS is validated for a wide range of matrices:
- Food and beverage
- Beer, wort, and malt
- Meat products
- Plastics and polymers
- Cereals, starch and alternative products
- Plant material
- Animal feed
- Soil, sediments, and fertilizers
- Milk and dairy products
Compliant with international ISO Standards
The Rapid N Exceed is compliant with ISO 16634-1 and ISO 16634-2
