Solid Phase Microextraction (SPME) is an efficient technique for isolating analytes from various matrices. This method integrates sampling, extraction, and analysis for on-site monitoring applications.

Area of Science:

  • Analytical Chemistry
  • Separation Science

Background:

  • Solid Phase Microextraction (SPME) is a versatile technique for analyte isolation and concentration.
  • It utilizes a sorbent-coated fiber to extract compounds from a sample matrix until equilibrium is reached.

Purpose of the Study:

  • To summarize the principles and applications of Solid Phase Microextraction (SPME).
  • To highlight its role in simplifying on-site analysis across diverse fields.

Main Methods:

  • SPME involves exposing a coated fiber to a sample matrix.
  • Analytes partition between the sample and the fiber coating based on their partition coefficient.
  • The extracted analytes are then desorbed for instrumental analysis.

Main Results:
