SPME is a unique sample preparation technique that eliminates most drawbacks to extracting organics. SPME requires no solvents or complicated apparatus. It can concentrate volatile and nonvolatile compounds (in liquids or gaseous samples), for subsequent analysis by GC or HPLC.
SPME offers some important advantages:
۱- Single Step Extraction – reduces sample preparation time by 70%
۲- Versatility – various selectivities available, adapts to any GC or HPLC system, can be automated
۳- Efficient & Economical – little/no use of solvents, quantitative method, allows more than 50 extractions per fiber on average
