Switching on the analyzer
NOTICE
Risk of device damage due to depleted copper wool
Damage to optical and electronic components of the analyzer due to aggressive combus-
tion products when the copper wool in the halogen trap is depleted!
¡
Only use the device with an operational halogen trap!
¡
Replace the complete filling of the halogen trap when half of the copper wool or
brass wool is discolored!
Before switching on the analyzer, check the following:
¡
The waste hose is connected to a suitable waste container or drain. Free flow is en-
sured. The capacity of the waste container is sufficient.
¡
The gas supply is connected in accordance with regulations and the inlet pressure is
400 to 600 kPa.
¡
There is enough phosphoric acid in the reagent bottle. A volume of 0.5 ml acid is re-
quired per TIC determination.
¡
The halogen trap is connected, filled with copper and brass wool. The copper and
brass wool not used up.
¡
All hoses are properly connected and in good working order.
¡
All optional accessories (autosamplers, solids modules, etc.) are connected.
Prepare the sample and switch on the analyzer as follows:
}
Open the valve on the pressure reducer of the gas supply.
}
Switch on the PC.
}
Switch on the other optional components.
}
Switch on the analyzer via the main switch. The status LED on the left front door
lights up in green.
}
Start the control and analysis software on the PC. Log in with username and pass-
word.
}
Answer the query Initialize analyzer? with [Yes].
ü
After successful login, the software initializes the analysis system and queries the
connected components. The measuring gas flow reaches its target value (160 ml/
min) after approximately 1 to 2 min.
}
If the analyzer is not ready for measurement after 30 min and one or more compo-
nents are still displayed in red in the System state window:
– Check the hose connections for proper fit and check for errors.
}
After each syringe change and after any manipulation of the locks such as changing
the catalyst, check the adjustment of the autosampler. If necessary, readjust the au-
tosampler.
}
After each syringe change: Enter the syringe size in the software.
– Open the Options, window, tab Analyzer components with menu option Configu-
ration |Edit options.
– Select the syringe volume in the Size list field.
}
For NPOC measurements: Set the NPOC purge flow.
The NPOC purge flow has been preset to 50 to 160 ml/min. The purge flow can be
increased or decreased dependent on the measuring task.
