            The core feature of the TOC-L series is the
            ISP      module       (Integrated     Sample
            Pretreatment). The ISP module consists of an        When filling the data of the calibration points,

            samples and enables the creation of dilution

            possibilities offered by the ISP module thus
            reduce the time expenditure by the user.
