Hot off the press - Introducing an efficient method for extracting over 100 semi-volatile organic compounds (SVOCs) from EPA 525.2/525.3 using our Mini-Disk with SPE-03 and Presto automated SPE systems.
Contaminants such as PAHs, PCBs, pesticides, and phthalates in drinking water pose significant environmental and health concerns, making their efficient extraction critical for regulatory compliance. EPA Methods 525.2 and 525.3 provide standard approaches for detecting SVOCs in water using SPE and GC-MS. This application note discusses results following each of their sample preparation techniques.
While traditional SPE disks enable faster sample loading and resist clogging, they require more solvent and have limited automation compatibility. SPE cartridges, on the other hand, are more accessible but operate at slower flow rates. PromoChrom’s MD-525-30 Mini-Disk bridges this gap by combining the advantages of both formats. It allows high flow rate while
using less solvent, making it an efficient solution for automated systems. When integrated with the SPE-03 or Presto systems, extraction times are significantly reduced - 137 minutes for the SPE-03 and just 79 minutes for Presto, with solvent use under 20 mL for fraction collection.
