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.
All SPME fibers have a standard length of 10 mm and a 23 gauge needle.
SPME arrows have a phase length of 20 mm but vary in diameter. A specific SPME arrow tool on the autosampler is required.
Ordering information: For method development, a set of each fiber or arrow type is available.
