Advantages of SPME Analysis Using Multiple Fibers for the Examination of Laundry Detergent

Solid Phase Micro Extraction (SPME) is a non-exhaustive sampling technique. SPME fibers are covered with different coatings of assorted thicknesses in order to extract analytes from the sample matrix. Often the coating and thickness is dependent on the analytes of interest. The ability to automate changing the SPME fibers in a sampling system is invaluable when the analytes of interest are diverse and require varied coatings for the sample extraction. The advantages of automated SPME fiber exchange will be examined in the application.
