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.
