Checking the function of the
detection module
Check the function of the detection module after maintenance via a control measure-
ment.
} Perform a purge measurement with a solvent, e.g., isooctane.
} Analyze a standard solution (5 mg/l TN
b
) Compare the curve and area with earlier
measurements.
} For resuming measuring operations: Determine the daily factor to test calibration. If
the daily factor is outside of the tolerance range, the analysis system must be re-cali-
brated.
14.10.2Replacing the absorber
ð Replace the absorber if the analysis baseline has been permanently raised. Replace
the entire absorber (replacement part).
} Remove the screw connection from the absorber. Do not pull the hose out of the de-
vice!
} Pull the absorber out of the holding clamps.
} Press the new absorber into the holding clamps. Reconnect the hose.
ü The detection module is ready for measurement again.
