The rapid OXY cube is a newly developed analyzer for highly precise and matrix-independent oxygen concentration measurement. Oxygen analysis using pyrolytic conversion poses high demands to instrument technology. To guarantee a highly precise and matrix-independent result, pyrolysis temperatures up to 1450 °C are necessary.
These extreme analysis conditions can only be fulfilled by rapid OXY cube, which achieves full conversion of sample oxygen to carbon monoxide. Even persistent organic as well as most inorganic substances are digested under these conditions and are detected matrix-independently. In addition, the novel backflush technology guarantees blank-free measurements also of the most difficult samples.
Highest temperature for highest precision
Our improvements in instrument technology lead to oxygen concentration analyses with unprecedented precision (standard deviation <0.1 % absolute) and convenience. The large dynamic measurement range allows sample weights of below 1 mg as well as up to 300 mg. The rapid OXY cube also stands for unmatched user-friendliness: It is optimized for unattended overnight operation and the pyrolysis reactor can be used for several thousands of samples.
The rapid OXY cube is optimized for oxygen analysis.
Low instrument background
Due to the novel reactor design with fully separated gas flows a very low background signal has been achieved.
Separation of carbon monoxide on a specific column for perfect separation without peak overlap and automatic optimization of the analysis time.
Specifically equipped with novel backflush technology to guarantee full nitrogen-carbon monoxide separation for highly accurate analysis of oxygen.

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.
