Application Note: Determination of AOX in wastewater samples by column method according to DIN EN ISO 9562
13 February 2023

In this application note from Analytik Jena, the provided measurement results show that sample preparation by column method provides reproducible AOX results for different types of challenging wastewater samples. Even samples with high particle loads and complex matrices (high salt and DOC levels) could be adsorbed onto activated carbon quickly and reliably. The APU sim sample preparation unit enables to process six samples simultaneously in less than one hour without manual intervention. Compared to the time and labor-intensive batch method, the AOX analysis according to the column method is faster and cost-effective.
