For NPOC determination
}
Prepare the detection module and the basic module as previously described.
}
Connect the NPOC purge hose (hose 16) to the "out ABD" connection on the basic
module.
}
Connect the purge hose with a hose with an outer diameter (AD) of 1.6 mm. Fasten
the hose to the rear on the TOC module.
}
Route the hose to the holder on the sampler. Alternatively, use the hose for manual
purging of the acidified samples.
For TC, EC/OC determination
The TOC module can be configured for TC determination with the basic module and the
multi-purpose combustion tube or the special combustion tube for EC/OC determina-
tion. For EC/OC determination, the special combustion tube for EC/OC determination
must be used. The measuring gas is routed directly from the combustion tube into the
NDIR detector via the "sample in" outlet.
}
Remove hose 82 from the "sample in" measuring gas inlet on the rear of the detec-
tion module.
}
Connect the "sample OUT N/S/C" outlet on the basic module with the "sample in"
measuring gas inlet with hose 9.
12.3 Operation
12.3.1 Operating the analysis system
}
Switch on the basic module and the detection module.
ü
The devices boot up. The status LED on the front of the basic module light up in
green after approx. 30 s.
ü
The LED on the front of the detection module flashes during the run-in period.
Depending on the detector, the run-in period can take up to 30 min. After this,
the LED will light up continuously. Starting a measurement is only then possible.
}
Open the gas supply and set the required gas pressure.
}
Switch on the PC.
