SPE (Solid Phase Microextraction)

Solid Phase Microextraction (SPME) is a technique used to analyze trace amounts of chemicals, like pollutants or flavors, in liquids, gases, or solids. It involves using a small, coated fiber that absorbs or adsorbs the target compounds from the sample without the need for liquids or solvents. After exposure, the fiber is inserted into a detector, such as a gas chromatograph, where the collected chemicals are released for analysis. SPME is efficient, reduces contamination risk, and simplifies sample preparation, making it a valuable tool in environmental testing, food safety, and forensic analysis.
