MAXimum performance in protein analysis

The rapid MAX N exceed is the first N/protein analyzer according to the Dumas method that utilizes the highly successful EAS REGAINER® technology also for larger sample weights. Designed for 24/7 unattended operation, the instrument addresses any high throughput laboratory facing a wide range of sample types and weights. The rapid MAX N exceed stands for outstanding precision, sensitivity and sample flexibility.

Ease of use
Save valuable time in sample preparation. The unique post-combustion technology ensures the complete digestion of even challenging species that are usually difficult to combust. Grinding or milling can therefore often be omitted without affecting reliable data quality

Highest sample throughput
The rapid MAX N exceed offers the fastest N/protein determination in 5 minutes. In conjunction with the 90 position autosampler it is possible to measure 300 samples per day. With the proprietary EAS REGAINER® technology it is possible now to run more than 1000 samples without the need to exchange reducing agent. Thus customers can enjoy outstanding low maintenance intervention for industry-leading system uptime.

Sample flexibility
The upright crucible design ensures an optimal combustion of any kind of liquid samples, such as milk, beer, soft drinks, juice, soy sauce, etc. Combined with the unique post-combustion technology a reliably high, matrix-independent data quality is achieved. Solid samples of 1 g can be measured with outstanding precision and accuracy.

Specifications:
Measuring method
High temperature combustion with 100% recovery and detection of the released nitrogen. 
For N/Protein “Dumas” analysis according to AOAC, DIN/ISO, EN and most relevant standards.

Easy sample handling
Direct weigh-in into re-usable crucibles (steel or ceramics) without any special pre-treatment. Suitable for solids or liquids up to several grams or milliliters.

Safe, fast, clean
The analysis takes only a few minutes. No aggressive or toxic chemicals required. Physical and chemical separation of water and and interfering gases.
