The TOC analyzers use the combustion-catalysis-oxidation method at 680°C developed by Shimadzu and now used worldwide. They offer an ultra-wide measurement range from 4 µg/L to 30,000 mg/L and are characterized by a detection limit of 4 µg/L, which is achieved through coordination with NDIR. This is the highest detection sensitivity available in the combustion-catalysis-oxidation method. In addition, this method enables the efficient oxidation of easily degradable, low molecular weight organic compounds as well as difficult to degrade, insoluble and macromolecular organic compounds. Measuring range: . 4 µg/L to 4,000 mg/L. Automatic dilution:. Unavailable. Measuring time for NPOC (total organic carbon without particles): (Without sampler): . Approximately 10.5 minutes; Sample is divided into vials -> acid added -> sample placed -> conditions set -> measurement. IC pretreatment:. Outgassing only, automated treatment outside the analyzer. Rinse water:. None, substitute rinsing with sample (rinse only with sample). COD/BOD conversion:. Function not available. Total nitrogen measurement:. Not available. Built-in LCD:. Black-and-white. Accuracy control function:. No. ER/ES (Event Registration/Event Storage): No. Number and type of data stored:. Measurement results: 200 average values of samples can be saved. Output of saved data:. Not available. NDIR light intensity adjustment:. Necessary. Detecting Carrier Gas Problems:. Function not available. Dimensions and weight of the main unit:. W480×D500×H480mm, approximately 46kg. Sample vial for the autosampler:. ASI-5000A: 5 mL×78, 42 mL×16 (as well as STD 8), special vials used. Simple autosampler:. Not set.
