Column Method

Adsorption of Organic Halogens onto activated carbon is part of the procedure for analyzing Adsorbable Organic Halogens or Total Organic Halogens. This can be done according the batch method or column method.

The column method is suitable for (waste)water samples which contain few particles. In any other case the batch method is needed. Multiple samples can be filtrated simultaneously through quartz glass columns, executed by a fully-automatic filtration system. After filtration, the Inorganic Halogens are removed by a Nitrate wash solution. Once the Inorganic Halogens have been removed, the activated carbon can be emptied in a quartz sample cup or introduced directly into an auto sampler. The activated carbon is transferred to the high temperature furnace and combusted.
