Analysis of carbon is also essential for drinking water, groundwater, and wastewater for compliance monitoring. TROUBLESHOOTING APOLLO 9000 TOC 1. High Baseline  No flow into the detector  Dirty combustion tube and catalyst  Dirty carrier gas supply  Incorrect zero adjustment on the NDIR How do you lower the baseline? No flow into the detector-make sure the gas flow is 200ml/min Check at the gas inlet to the combustion and at the vent Dirty combustion tube and catalyst Dirty carrier gas supply Connect the carrier- gas directly to the NDIR (make sure the gas flow is 200ml/min) If the baseline drops the combustion tube and the catalyst need to be cleaned If the baselin Less
