There is one excellent study on the optimization of this method for 46 compounds including pesticides, PAHs, and other contaminants on the EPA list (Raisglid et al., 1993). Raisglid and co-workers optimized the 525.1 Method using an automated workstation made by Tekmar called the AutoTrace SPE Workstation (see Chapter 10). The automation parameters discussed in this study will be addressed later in Chapter 10. 

The use of automation results in fast, easy, and reliable methods for SPE. There are a number of instruments available for totally automated SPE, as well as automated methods development of SPE, which span the spectrum in cost. In environmental applications, the choices of automation are limited, with only the Autotrace by Tekmar available for large-volume samples (1 L). In the area of on-line SPE-HPLC, nearly all of the workstations for SPE have the option for direct injection into the HPLC. For on-line SPE-GC/MS, there are several instruments and methods available (a modified PROSPEKT, Varian automated SPME, and the Hewlett-Packard solid-phase extraction workstation). For total automation including addition of internal standards, derivatiza-...
