5.2.2.3 Spill Threshold
If the value of TOC exceeds this % of the analyzer's range, the analyzer will

between 0 and 99 minutes.

If the TOC level exceeds the spill threshold, the analyzer will clean for the spill
recovery time. Following the clean, it will purge and then go online to measure
the alternate stream.
