SPME fibers and arrows

Dodavatel: Thermo Fisher Scientific
Popis: Solid Phase Micro Extraction (SPME) uses a thin-fused silica fiber coated with a sorbent which enables extraction of compounds of interest from liquid or gaseous samples through absorption or adsorption. The fiber is then moved to the injector and the compounds thermally desorbed. The SPME consumables come in two formats SPME fibers and SPME arrows.
