If inorganic carbon is present it can be eliminated by direct acidification with dilute hydrochloric acid or indirectly by exposure to concentrated sulphurous acid vapour. Where samples are submitted for total organic carbon (TOC) we will pre-treat your samples in this way to remove any inorganic carbon. Total inorganic carbon (TIC) is determined by difference from the total carbon and total organic carbon values.
