Increase laboratory efficiency at significant lower price-per-sample. 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.
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.
The rapid MAX N exceed is optimized for N/protein analysis.
For high sample weights, the Strong Mode with a maximum adsorption capacity of 500 mg carbon of the Purge and Trap columns is available.
Fast Mode For a faster analysis time, the Fast Mode with a maximum adsorption capacity of 100 mg carbon of the Purge and Trap columns is available.
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.
Large concentration range
from 20 ppm to 100% or 300 mg absolute N content.
Few operational requirements
Less than 1 m laboratory working space, 1 electrical connection and 2 operating gases are sufficient for maintenance free long term operation. Operation with helium or argon carrier gas are standard.
With integrated 90 sample changer, control through Windows® based operating software. Optional 21 CFR Part 11 compliant software.
High temperature elemental analysis of
C, S, O, N, and H in inorganic materials
For the first time in history of inorganic elemental analysis it is possible to analyze 5 elements in 1 analyzer. The newly developed and worldwide unique inductar EL cube sets new standards in flexibility and precision with its innovative solutions and state-of-the-art technology. It is equipped with a long-life solid-state high-frequency induction furnace, which makes it possible to reach a sample temperature of up to 3000 °C. Thanks to an optional camera the gas release can be observed in real-time by the operator. Also for the element detection new technologies are used. Carbon, sulfur and oxygen are analyzed with a wide-range IR detector, which are capable to detect the whole concentration range. For the precise determination of hydrogen an innovative detection technology finds usage for the first time. The concentration of the fifth element nitrogen is detected via TCD.
Dissolved carbon and nitrogen isotope analysis on the highest level
Based on the “cube” platform that has set the gold standard for elemental analysis, theiso TOC cube is a new concept for the quantitative and isotopic determination of dissolved carbon and nitrogen in liquids and slurries.
The simultaneous determination of dissolved δ13C and δ15N at concentrations as low as 0.2 ppm and 10 ppm, respectively, are easily achieved with the vario iso TOC cube. For the first time the high sensitivity for measuring TOC or TNb in aqueous solutions is combined with the accuracy and reliability of organic elemental analysis to automatically measure up to 100% carbon concentrations in matrices ranging from dilute glacial meltwaters to aggressive soil extracts. Oxidation of bound carbon and nitrogen by means of high temperature digestion and catalytic post combustion in a free selectable range of up to 1,200 °C, with reduction of nitrogen oxides to N2 for determination by IRMS.
With measuring modes for the isotopic analysis of TC/TIC, DOC, TC/TIC/TNb or DOC/TNb. Formed CO2 and N2 are purified through a halogen trap with subsequent 3-step intensive gas drying system, and a newly developed matrix separation system (patent pending) that allows multiple injections of difficult matrices (such as seawater). CO2 is detected by a super wide range NDIR-photometer with extraordinary linearity prior to peak focusing of both CO2 and N2 on individual temperature programmed desorption columns (patent pending) to achieve the high-level performance required for IRMS measurement.
