Despite its efficacy, SPE encounters challenges in non-drinking water matrices where solid particles can obstruct SPE cartridges, prolonging extraction or necessitating multiple cartridges per sample. EPA Method 1633 recently introduced glass wool to address this issue; however, manually adding wool can be laborious and inconsistent. This presentation introduces an integrated filter aid for SPE cartridges, enhancing consistency compared to glass wool.
