ABSTRACT
A new polymeric sorbent has been developed for solid phase extraction of different classes of compounds, including acids, bases, neutrals, and even some mid-polar to polar compounds, which are often not well retained by silica based sorbents, such as C8 and C18. This new polymeric sorbent is applicable to multiple EPA water extraction methods, including EPA method 526 (semi-volatile organic compounds), method 527 (pesticides and flame retardants), method 528 (phenols), methods 529 and 8330 (explosives), method 537 (perfluorinated alkyl acids), and method 553 (benzidines and nitrogen-containing pesticides). This poster will present the analytical performance of this new sorbent to extract phenols (method 528), explosives (method 529), and other analytes, such as bases and polar compounds in water samples. Excellent recoveries and consistent extraction performance with minimum lot-to-lot variations were obtained. The results have demonstrated the superior extraction properties of this new polymeric sorbent in various applications for acids, bases, and neutrals with different polarities.
