ABSTRACT
Solid Phase Extraction (SPE) is one of the most diverse sample prep media available. With a wide array of sorbents and packaging platforms available, there are literally limitless possibilities for sample prep procedure. For many complex analyses, multiple sorbent beds are desired for both sample extraction and extract purification. Traditionally performed manually, where different cartridges are connected and later separated, automation can allow for hands free extractions. The usage of automated, multi-cartridge SPE was performed for a variety of matrices and analytical methods to streamline efficiencies into single, programmable prep methods. Extractions performed included Semi-Volatiles in waste water (EPA625/8270), multi-cartridge pesticide extractions for dissimilar compounds, Organochlorine pesticides with in line Florisil clean-up (EPA8081 & EPA608), PBDEs with inline acidified silica gel clean-up (EPA1614A). Parameters tested include precision and accuracy tests, matrix effects on performance, real matrix MDL studies and liquid-liquid extraction (LLE) comparisons.
