Determination of AOX in wastewater samples by column method according to DIN EN ISO 9562
13 Feb 2023In 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.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats. Find the best SPE, SLE and SPME equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Waste WaterWater AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).
