The April 2003 CSSC meeting will be our Annual Meeting. The CSSC officers and vacant Board of Directors seats will be elected by our membership at this meeting. Also, changes to our bylaws will be voted on by our membership. There will be a dinner and presentation following the annual meeting. The dinner will be a buffet meal consisting of chicken, roast beef, seafood newburg, roasted potatoes, coffee and dessert. To register, contact Jason Leonard by email at secretary@cssconline.org. |

| Abstract: In many laboratories, the preparation of samples still represents one of the more time-consuming, labor-intensive, and error-prone steps in the analytical cycle. Many manual sample preparation methods have been used for decades with little or no improvement. Newer techniques that are faster, safer, easier to carry out, providing better or equivalent recovery and reproducibility, more easily automated, and use smaller amounts of sample and organic solvent are receiving increasing attention. Solid-phase extraction (SPE) is one such technique that has seen a rebirth in recent times due to its many advantages. The strong interest in combinatorial chemistry, the screening of new drug candidates, ever increasing environmental sampling, food safety and high-throughput sample cleanup has spurred developments in solid-phase extraction. Recently, SPE has received a great deal of attention with the development of 1) new formats, such as the disks, 96- and 384-well SPE plates, and SPE micropipette tips; 2) highly selective-, application-specific-, stable polymeric-, and water-wettable phases with new chemistries; and 3) new techniques such as matrix solid-phase dispersion (MSPD), solid-phase microextraction (SPME), and stir-bar sorptive extraction (SBSE). The automation of SPE has also seen rapid development with dedicated units for the isolation of drugs from biological fluids, autosamplers with SPE capability for conventional and 96-well plate formats, and robotic workstations that, in addition to SPE, provide an increased level of laboratory automation. On-line SPE-HPLC column-switching systems using high-pressure, low-volume valving and “in-tube” liquid extraction systems have also been used to increase sample throughput as an alternative to automation of the SPE experiment. The increased use of LC-MS and LC-MS/MS systems and sample matrix compatibility requirements has also contributed to more rapid and efficient methods of off-line and on-line sample cleanup. This lecture will focus on the newer manual and automated SPE technologies that are currently being applied or are on the horizon to become routine methods. |
