Vocabulary Term Details

Non-purgeable organic carbon

Definition (http://www.hill-laboratories.com/file/fileid/48175)

All the carbon present after the sample has been acidified and purged with purified air to remove inorganic carbon. Note that volatile organics such as volatile fatty acids (VFA), light hydrocarbons (eg petrol) and some solvents (eg acetone) will be lost during the purging. It is common but incorrect, for laboratories to measure NPOC, but report it as TOC.
