Extraction of a Full Suite of Semivolatile Compounds from Drinking Water Using Automated Solid Phase Extraction

US EPA method 525.2 may use solid phase extraction (SPE) to extract the analytes of interest from water samples. It includes a variety of quality control measures to ensure the method is under control throughout the analysis. The Biotage® Horizon 5000 was used in this study to extract the EPA Method 525.2 analytes from six prepared water samples. The Atlantic high-capacity C18 disks provided excellent recovery of the large suite of compounds extracted in water. The Biotage® Horizon 5000 system provided uniform performance and a hands-off approach to the extraction step. The reproducibility of the six runs was excellent and the average of the standard deviation values was 2.57%.
