Activated carbon has a large internal surface making it ideal for adsorption purposes. During the sample preparation of AOX/TOX samples, activated carbon is used to adsorb the Halogen content present in a water sample.
After adsorption, the activated carbon is placed in a quartz-glass frit or directly introduced into a sample boat, and combusted at 1000 ˚C. The Xplorer measures the amount of AOX/TOX present in the sample based upon microcoulometry detection technique.
