With the new acquray series Elementar opens an entirely new way for easy Total Organic Carbon (TOC) analysis and more. The technology is based on a chemical oxidation process supported by highly energetic UV radiation. This combination ensures complete digestion of all organic compounds. The modular concept allows the attachment of optional extra modules for the determination of TOC in solids, Total Nitrogen (TN) in water and Total Phosphorus (TP) in water.
The instrument comes with predefined methods, completely calibrates itself automatically and auto-alerts the user any time maintenance is needed. This makes the acquray series the ideal solution for routine labs that require instruments with high laboratory efficiency and minimal down-time.
The acquray series, with its modular concept, offers an industry-leading versatility. Starting from the TOC analyzer base module, additional extra modules can be attached at anytime. For increased sample throughput, an autosampler unit is available, offering several carousels for different sample vial sizes. An optional combustion furnace for solid samples can be used either for the classical TOC analysis of solids via acidification prior to combustion, or for the more advanced method via temperature ramping without acidification. Completing the package, another two unique modules are available that enable the determination of Total Nitrogen in water and Total Phosphorus in water. Thus, acquray is the world’s first UV-digestion TOC analyzer with a Total Nitrogen and/or a Total Phosphorus option (patent pending).
A workhorse for any laboratory The acquray series is designed for maximum robustness and minimal maintenance effort, thus providing industry-leading system uptime. For unattended overnight operation, optional autosampler configurations with up to 109 positions are available.
Ease of use
The acquray series is optimized to significantly simplify the daily routine operation. Clearly arranged, easily accessible system components minimize maintenance efforts. Thus, customers can enjoy smooth analyses and confidence in their results.

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.
