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.

The influence of vine training and sunlight exposure on the 3-alkyl-2-methoxypyrazines contents in musts and wines was studied by means of two previously reported methods based on headspace solid-phase micro-extraction. Experimental samples were monitored throughout grape ripening and wine making.


GC/MS/MS Analysis of Bisphenol A (BPA) in a Fruit Flavored Energy Drink on the SLB-PAHms Column After SPME Using an Overcoated SPME Fiber

Bisphenol A (BPA) plastic is controversial in food and beverage containers. This study demonstrates SPME of BPA from an energy drink using an overcoated PDMS/DVB fiber, followed by GC/MS/MS analysis using SLB-PAHms GC Column.

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.
