Performance in TOC analysis meets ease of use
The technology of the acquray® is based on a wet-chemical oxidation process supported by highly energetic UV radiation. This combination ensures complete digestion of all organic compounds and leads to precise measurement results. The modular concept allows the attachment of optional extra modules to the total organic carbon (TOC) base module for liquid samples. Modules for the determination of TOC, residual oxidizable carbon (ROC) and total inorganic carbon (TIC) in solids, total nitrogen (TN) in liquids and total phosphorus (TP) in liquids can be flexible attached anytime. The instrument comes with predefined methods, easy, intuitive calibration procedures and auto-alerts you when 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 by low investment costs.
Features
Highest sensitivity for precise measurement results
The acquray is capable to handle high injection volumes up to 40 ml. In combination with the precise infrared detector (IR), the use higher injection volumes leads to a very low limit of detection of only a few ppb. The technology of the acquray is based on a wet-chemical oxidation process, that is supported by highly energetic UV radiation at different wave lengths. This powerful UV/persulfate digestion ensures complete digestion of even very stable organic carbon compounds and leads to highly accurate measurement results.
Outstanding instrument flexibility for your analytical needs
The acquray series with its modular concept offers an industry-leading versatility. Additional extra modules can be attached to the TOC base module at any time. For high sample throughput, an autosampler is available, offering several carousels for different sample vial sizes. An optional module with a powerful dynamic furnace for solid samples can be used either for the advanced TOC400, TIC900 and ROC analysis of solids via temperature ramping or classic TOC determination in pre-acidified samples at 900 °C. Completing the package, another two unique modules are available that enable the determination of total nitrogen (TN) in liquids and total phosphorus (TP) in liquids. Thus, acquray is the world’s first UV/persulfate TOC analyzer with a TN and/or a TP option.
Easy & fast analyses for daily routine operation
The acquray series is designed for maximum robustness and minimal maintenance effort, thus providing industry-leading system uptime. The clearly arranged, easy-accessible system components minimize time-consuming maintenance work. The intuitive, user friendly software offers easy control the instrument, easy calibration features and auto-alert functions for maintenance intervals. This makes it incredibly easy to perform analyses with the acquray.
Time saving sample preparation & autosampler
The autosampler with up to 111 positions is optimized for safe, unattended 24/7 overnight operation. Just prepare your samples and start the analysis before you finish your day and see your analysis results the next morning. Furthermore, the autosampler offers automated acidification for the measurement of the non-purgeable carbon (NPOC), making sample preparation easier, safer and faster. Thus, you can enjoy smooth analyses and confidence in your results.
