MAXimizing sample variety and throughput in nitrogen and protein determination

The rapid MAX N exceed PLUS is a high-performance nitrogen and protein analyzer designed for maximum laboratory efficiency and high sample throughput. Operating according to the safe, simple, and eco-friendly Dumas combustion method, it delivers fast and cost-effective nitrogen and protein determination in just five minutes per sample. Engineered for unattended 24/7 operation, its advanced crucible technology enables flexible analysis of a wide variety of sample types and weights up to 5 g / 5 ml, while optimized consumables and the use of argon as alternative carrier gas significantly reduce cost per sample. The ideal solution for laboratories with the highest demands on efficiency, flexibility, reliability, and continuous high-throughput performance.

Smart workflows in the intuitive software, automatic system checks, and tool-free maintenance ensure simple operation

Reliable results - anytime

Matrix-independent calibration as well as optimized sample introduction and complete combustion of the whole sample always ensure highest precision and accuracy

Nitrogen and protein analyzer rapid MAX N exceed PLUS

The rapid MAX N exceed PLUS is a compact crucible analyzer designed for maximum laboratory efficiency and high sample throughput.

All major components are easily accessible through the front door.

The slide-out furnace guarantees a comfortable working posture during maintenance tasks.

The rapid MAX N exceed PLUS' reusable steel crucibles have a capacity of up to 5 g / 5 ml - ideal for all different types of liquid, semi-liquid, and solid samples.

The 90-position autosampler can be reloaded at any time, enabling urgent samples to be prioritized even during an ongoing measurement run.

With optimized navigation, smart workflows, and clear traceability, the exceed PLUS software provides precise and efficient support for your everyday laboratory analysis.

A status display embedded in the front door of the rapid MAX N exceed PLUS signals when the system is ready or needs maintenance.

For maintenance tasks such as tube replacement, the furnace of the rapid MAX N exceed PLUS can be conveniently slid out.

All maintenance tasks can be performed tool-free thanks to user-friendly clamp connections.

Features

Maximum sample flexibility

Analyze a wide range of sample types with confidence. The upright crucible design with a capacity of up to 5 g / 5 ml allows laboratories to process a wide range of sample types - from liquids such as milk, beer, soft drinks, juice, and soy sauce to semi-liquids like yogurt and mayonnaise, and solids including meat, cereals, and flour with ease. Combined with our unique post-combustion technology, complete and unmatched combustion of even challenging sample matrices is ensured.

Best-in-class sample throughput

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. The 90-position autosampler can be reloaded at any time to prioritize urgent samples and offers nitrogen and protein determination in just five minutes per sample run.

Easy to use
The rapid MAX 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 MAX N exceed PLUS ensures outstanding precision and accuracy in nitrogen and protein determination. Thanks to the controlled oxygen jet-injection directly into the active zone and the industry-proven, catalytic post-combustion, complete combustion of the whole sample is guaranteed, even for samples hard to digest. The rapid MAX N exceed PLUS delivers matrix-independent results and offers absolute accuracy and full recovery in the low ppm range.

Future-proof with a 10-year commercial guarantee

Thanks to the outstanding robustness and longevity of the rapid MAX N exceed PLUS, we provide a 10-year commercial 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.
