Solid Phase MicroExtraction (SPME) is a technique in which a short fiber coated with a sorbent or polymer quantitatively extracts analytes from a sample matrix. The fiber is then sent to the injector of an instrument such as a Gas Chromatograph (GC) where desorption of the analytes occurs. For this reason, thin septa are highly recommended for SPME instruments. Catalog number 95025-04-1S is a recommended crimp cap for use with SPME. Catalog number 95025-04 is recommended as septa. As for vials, catalog number 95025-SPME is ideal for SPME use.
