MAXimum performance in protein analysis
Elementar’s rapid MAX N exceed is the first Dumas method N/protein analyzer that utilizes the highly successful EAS REGAINER® technology for larger sample weights.
Drawing on Elementar’s decades of expertise, the instrument offers increased laboratory efficiency at a significantly lower price per sample. The rapid MAX N exceed stands for outstanding precision, sensitivity and sample flexibility, while its 24/7 unattended operation addresses the challenges faced by any high-throughput laboratory dealing with a wide range of sample types and weights.
Its use of the crucible technique makes it a low-maintenance instrument, while inputting sample weights up to 5 g reduce the homogenization process.
Ease of use
The unique post-combustion technology ensures the complete digestion of even the most challenging species, omitting the need for grinding or milling without affecting reliable data quality. This helps you save valuable time in sample preparation.
Highest sample throughput
The rapid MAX N exceed offers N/protein determination in just five minutes, while the 90-position autosampler makes it possible to measure 300 samples per day. By utilizing EAS REGAINER® technology, users can run more than 1,000 samples without the need to exchange the reducing agent, meaning customers can enjoy outstanding low-maintenance intervention for industry-leading system uptime.
Sample flexibility
The upright crucible design ensures optimal combustion of any kind of liquid samples, including milk, beer, soft drinks, juice and soy sauce, while solid samples of 1 g can be measured with outstanding precision and accuracy. The inclusion of unique post-combustion technology allows reliable, efficient and matrix-independent data collection to be achieved.
Future-proof investment
A 10-year warranty on the analyzer’s furnace and thermoconductivity detector (TCD) showcases its outstanding robustness and longevity, while our commitment to providing spare parts for a decade highlights our well-known long-term dedication to technical support. This combination results in an outstanding low cost of ownership and gives customers confidence in their return on investment.
Measuring method:
The instrument offers high-temperature combustion with 100% recovery and detection of the released nitrogen. It can be used for N/protein Dumas analysis, according to AOAC, DIN/ISO, EN and most relevant international standards.
Easy sample handling:
Directly weigh in reusable crucibles, such as steel or ceramics, without any special pre-treatment. Suitable for solids or liquids up to several grams or milliliters.
Safe, fast and clean:
The analysis takes only a few minutes and there is no need for aggressive or toxic chemicals to physically and chemically separate water and interfering gases.
Large concentration range:
The concentration range measures from 20 ppm to 100% or 500 mg absolute N content.
Low operational requirements:
The instrument takes up less than one meter of laboratory working space and only needs one electrical connection and two operating gases for maintenance-free, long-term operation. Uses helium or argon carrier gases as standard.
Fully automatic:
Control the integrated 90-sample charger through Windows-based operating software or optional 21 CFR Part 11 compliant software.
