Improved Recoveries of Polycyclic Aromatic Hydrocarbons (PAHs) as Defined in EPA 550.1 and Simultaneous Removal of Humic Acids from Water Using Strata® PAH
25 Feb 2013In this application note it is shown that polycyclic aromatic hydrocarbon compounds (PAHs) can be effectively extracted from water samples using Strata PAH. In addition it is shown that humic acids, which often interfere with chromatographic separation, can be removed from the sample using the SPE sorbent, Strata® PAH. The Strata PAH provides consistent, high recoveries of all 16 analytes listed under EPA Method 550.1.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.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.
