N-Realyzer - Nitrogen and protein determination according to the Dumas method

Experience the intuitive, precise, fast and safe nitrogen and protein analysis with the N-Realyzer:

Intuitive operation: Self-explanatory user interface and automated process management make everyday laboratory work easier.
Functional instrument design: High-quality materials and tool-free operation guarantee a long service life and easy maintenance.
High work safety: Daily work and maintenance steps can be carried out safely thanks to the optimised workflows in the system.
Wide range of samples: Analysing up to 100 samples in series, both solid and liquid samples, guarantees maximum throughput - regardless of the nitrogen content.
Resource-efficient operation: Factors such as sample-optimised oxygen addition make operation as resource-efficient as possible, so that the costs per sample are low and everyday laboratory work is as economical as possible.

REAL-OS - Nitrogen determination made easy

The operating status of the N-Realyzer is always visible via the defined colour system of the REAL-OS user interface. Thanks to the intuitive structure, you can navigate effortlessly through the user interface. In addition, thanks to network integrity and web browser architecture, you can access the device from any computer in the company network and have everything in sight at at all times.

The REAL-OS software integrated in the N-Realyzer offers automated management of all operating modes. This is made possible by a customisable schedule in which the operating times are defined. N-Realyzer is thus optimally integrated into your daily work routine. Thanks to the automatic checking of all relevant parameters, you only need to define the work steps and the device takes care of the rest. With its sophisticated user group management and audit trail, the N-Realyzer complies with FDA 21 CFR Part 11 and ISO 17025, making it the ideal system for any certified laboratory.

Downtime due to maintenance work? No problem for the N-Realyzer

N-Realyzer sets standards in terms of availability, service and durability thanks to its ingenious design. The fast replacement of all process-relevant components during operation saves working time and ensures smooth operation.

The use of high-quality materials and the carefully considered system design not only guarantees precise analysis, but also easy maintenance and service. The tool-free sealing concept enables all consumables to be replaced quickly.

Determine nitrogen and protein content - more secure than with the Kjeldahl method

Nitrogen determination using the Dumas method takes place in a compact, closed system, mainly without the use of hazardous chemicals. This in turn leads to more space and work safety in the laboratory. You can use your fume cupboard flexibly for other tasks and systems.

A faster analysis time and more efficient sample preparation than with the Kjeldahl method lead to considerable time savings and significantly lower operating costs.

Overall, a nitrogen analyser using the Dumas method offers a modern, cost-effective, time and space-saving alternative to traditional Kjeldahl systems.

Large sample variety provides highest flexibility

Whether solid or liquid, with a high or low nitrogen content: N-Realyzer delivers reliable and precise results for up to 100 samples in series for any sample matrix. The patented autosampler prevents samples from being mixed up. Thanks to the high variability in the sample sequence, you can flexibly "insert" urgent samples.

80 % solid samples today and 70 % liquid or pasty samples tomorrow? No problem for N-Realyzer. Thanks to the 2-stage water separation, the water content of aqueous samples is completely removed. Your benefit: You can analyse aqueous samples in series without risking the failure of your device.

Low operating costs for nitrogen analysis are guaranteed

As a carrier gas, helium is still the gold standard for determining the nitrogen and protein content. This allows you to achieve higher accuracy and better reproducibility than with systems that use argon or CO₂ as a carrier gas. However, as the targeted use of argon can save operating costs, the N-Realyzer has a helium-saving function. This allows N-Realyzer to be switched from helium in operating mode to argon in standby mode. This allows you to maintain the analytical quality and optimise the use of both gases.

The N₂ detector in the N-Realyzer is designed to work with high precision without the usual reference cell. Your benefit. The nitrogen analyser uses 50 % less helium than other systems. This saves you 10 % to 50 % of the costs for carrier gas, even compared to systems that work with argon or CO₂.

Sample-optimised oxygen addition significantly reduces consumption and increases the service life of your O₂ cylinder
