Lowest cost of ownership in nitrogen and protein determination
The rapid N exceed PLUS is a compact nitrogen and protein analyzer designed for laboratories that prioritize maximum cost efficiency without compromising analytical performance. Operating according to the safe, simple, and environmentally friendly Dumas method, it delivers fast and reliable nitrogen and protein determination in just 3–4 minutes per sample. Engineered for low cost of ownership, the analyzer uses CO₂ as a cost-efficient carrier gas and minimizes consumables consumption, resulting in the lowest cost per sample in its class. Despite its compact footprint, the instrument offers excellent detection sensitivity and maximum measurement accuracy for sample weights of up to 1.5 g / 1.5 ml. The ideal solution for laboratories seeking reliable nitrogen and protein analysis with minimal operating costs.

Features
Lowest cost of ownership
The rapid N exceed PLUS is designed to minimize operating costs without compromising analytical performance. By using CO₂ as a cost-efficient carrier gas and reducing consumables consumption through advanced EAS REGAINER® technology and extended consumable uptime, the analyzer achieves an exceptionally low cost per sample. Combined with fast analysis times of up to four minutes and high measurement accuracy, laboratories benefit from reliable nitrogen and protein determination while keeping long-term operating costs to a minimum.
Fast analysis, fast results
The rapid N exceed PLUS realizes rapid nitrogen and protein determination in just 3–4 minutes per sample. Quick daily maintenance routines and less time-consuming calibration measurements significantly reduce setup time – saving you time every day and increasing throughput of real samples.
Easy to use
The rapid N exceed PLUS is designed for simple, reliable day-to-day operation. Improved process control and software with optimized navigation and smart workflows guide users efficiently through every step of the analysis. A status display directly on the instrument, automatic system checks, and integrated software assistants ensure quick preparation for analysis and smooth operation. Additionally, advanced EAS REGAINER® technology, extended consumable uptime and easy, tool-free replacement of pre-filled tubes simplify routine tasks. Using the Dumas combustion method eliminates the need for hazardous chemicals, making operation safer and more convenient for laboratory staff.
Reliable results - anytime
The rapid N exceed PLUS guarantees outstanding precision and accuracy through controlled oxygen jet-injection directly into the active zone and an industry-proven, catalytic post-combustion. This leads to matrix-independent results for even hard to digest samples. No need for time-consuming, frequent calibrations or expensive matrix-specific standards. All this results in reliably high data quality and a detection limit in the low ppm range.
Future-proof with a 10-year commercial guarantee
Thanks to the outstanding robustness and longevity of the rapid N exceed PLUS, we provide a 10-year commerical guarantee on the high-temperature combustion furnace and the thermal conductivity detector cell of the thermal conductivity detector (TCD). With our long-term oriented dedication to technical support, we provide spare parts for a minimum of 10 years. This results in outstanding low total cost of ownership, giving you confidence in return of investment.
