Analyze Nitrogen and Protein With the rapid MAX N exceed

With the rapid MAX N exceed, laboratories can analyze nitrogen and protein more efficiently. Designed using the secure, uncomplicated, and environmentally conscious Dumas combustion technique, the rapid MAX N exceed nitrogen and protein analyzer enables quick and economical determination of nitrogen and protein content, all within a five-minute timeframe.

The analyzer, which is designed for unsupervised 24/7 operation, satisfies the needs of any high-throughput laboratory dealing with a wide range of sample types and weights. The rapid MAX N exceed ensures exceptional accuracy, sensitivity, and sample flexibility, allowing users to increase the laboratory efficiency of their nitrogen and protein analysis.

Highlights of the rapid MAX N exceed

Maximum Sample Flexibility

The upright crucible design and distinct post-combustion technology provide maximum sample flexibility for a broad range of sample matrices.

Simplified Sample Preparation

Sample preparation is simplified thanks to the huge weighing ranges and sample volumes of up to 5 g / 5 ml.

Highest Sample Throughput

Fast analysis (5 minutes) and low maintenance allow for the highest sample throughput.

Lowest Cost per Sample

The EAS REGAINER® technology and the option of using argon as a carrier gas results in the lowest price per sample.

Maximum Sample Flexibility Due to Crucible Design and Unique Post-Combustion Technology

The rapid MAX N exceed’s upright crucible design allows nitrogen and protein analysis of any sample, from liquids like milk, soft drinks, beer, soy sauce, juice, and so on, to semiliquids like yogurt and mayonnaise, to solids like cereals, meat, and flour. Coupled with Elementar's post-combustion technology, complete and unmatched combustion of even challenging sample matrices is ensured.

Simplified Sample Preparation Through Largest Weighing Ranges and Sample Volumes

With a substantial 5 g / 5 ml capacity, the reusable, durable steel crucibles of the rapid MAX N exceed ensure convenient sample preparation for extensive weighing ranges and sample volumes during nitrogen and protein analysis.

Highest Sample Throughput Due to Low Maintenance and Fast Analysis

The rapid MAX N exceed provides the fastest nitrogen and protein determination in as little as five minutes. Its 90-position autosampler, which can be reloaded at any time, makes it simple to prioritize urgent samples during a measurement run.

Over 1,000 samples can be run without changing the reducing agent, thanks to the inventive EAS REGAINER® technology. Furthermore, the plug-and-play pre-filled EAS REDUCTOR® tube, which is used for reduction, saves valuable time.

As a result, nitrogen and protein analysis systems operate at industry-leading uptimes with exceptional low-maintenance intervention. The slide-out furnace and the user-friendly clamp connections system also assure tool-free maintenance and a comfortable working position.

Lowest Cost Per Sample, Thanks to EAS REGAINER® Technology and Argon as Carrier Gas

One of the most expensive aspects of traditional Dumas nitrogen and protein analyzers is the reduction of metals required to bind excess oxygen and convert nitrogen oxides to molecular nitrogen.

However, with Elementar's patented EAS REGAINER® technology which is integrated into the rapid MAX N exceed, this cost can be dramatically reduced.

In continuous flow, the reducing agent EAS REDUCTOR® is regenerated during each combustion phase by the inexpensive EAS REGAINER®, enabling the analysis of up to 1,000 samples before the EAS REDUCTOR® needs to be replaced.

This, in combination with the use of argon instead of helium as a carrier gas, means that the rapid MAX N exceed is able to achieve the lowest cost per sample in nitrogen and protein analysis. 

Future-Proof Thanks to 10 Years Guarantee

Due to its remarkable strength and long-lasting nature, the rapid MAX N exceed has a 10-year guarantee on the high-temperature combustion furnace and the thermal conductivity detector cell of the thermal conductivity detector (TCD).

With a long-term dedication to technical support, Elementar provides spare parts for a minimum of 10 years. This results in an outstanding low total cost of ownership, giving users confidence in their return on investment.
