General description

A new development in SPME fiber technology incorporates a protective overcoating on the fiber. This overcoating, which consists of polydimethylsiloxane (PDMS) serves as a barrier to protect the fiber from the matrix, which makes it more physically robust and less prone to chemical fouling. High background samples, such as many foods, pose a challenge to immersion SPME due to the presence of fats, sugars, pigments, and other macromolecules. These can stick to the SPME fiber and reduce its usable life and/or be transferred to the GC, where they may interfere with chromatographic analysis. Overcoating the fiber with PDMS reduces these problems.

Analysis of Bisphenol A in Food by Solid Phase Microextraction Using an Overcoated Fiber

Bisphenol A (BPA) is suspected to be an endocrine disruptor. Regulations on specific migration limits (SML) from food contact materials are getting tighter (EU 2018/213) requiring more sensitive determinations. An overcoated SPME fiber provides the durability necessary for direct immersion into foods such as canned soup and pumpkin, allowing for low level analysis of BPA via SPME-GC-MS/MS.
