            ■ TOC-L                                             ■ Example: River water
            To prepare  the sample  accordingly, the ISP
            module of the TOC-L  automatically acidifies             20
            the sample and strips the CO 2 originating
            from the TIC.                                            14

            The excellent particle tolerance of the                Signal[mV]
            analyzers  enables analysis of particle-                 7
            containing   surface   waters.   Using    the
            automatic    dilution  function,   multi-point
            calibrations  can be generated from a single             0
            standard. In the investigation of unknown                -2  0                   5
            surface waters or groundwater, one of the
            samples may exceed the calibration range. In        NPOC-Method
            this case, the TOC Control-L software offers        Acidification: 1,5%
            an option for automatic dilution  to bring  the     Sparge-time: 5 Minutes
            sample back within the calibration range.
