SCA-130-106



            ■ Particle tolerance of the TOC-L series            ■ Settings
            This test was carried  out using  a TOC-L             Injection volume 90 µL
            system (TOC-L CPH including ASI autosampler           TC measurement for the particle test
            with integrated stirring option).                     NPOC measurement in the autosampler
                                                                  Stirrer in the ASI-L,
                                                                  medium stirring speed
                                                                  No multiple injection

                                                                Used Cellulose-Standard:
                                                                Cellulose powder MN 100
                                                                Particle size: 20-100µm
                                                                Supplier: Machery-Nagel

                                                                ■ Results
                                                                The cellulose suspension was injected five
            ■ System Configuration                              times according to the above settings.
            -   TOC-L CPX
            -   ASI-L (40ml recommended) with particle          NPOC = 98,4 ± 2,2 mg/l (RSD = 2,27 %).
                needle l                                        This corresponds to a recovery of 98,4 %.
            -   Stirrer option                                  .
            -   Offline-Port can be used too

            The TOC-L CPH was first calibrated  using the
            automated dilution function in the range of 10
            – 100 mg/L.
