A direct immersion SPME method using a new overcoated SPME fiber was developed for the extraction of pesticides from pureed prune baby food.
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.

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.
Solid phase microextraction (SPME) is a solvent-free sample preparation technique that uses coated fibers to extract analytes of interest from a sample before analysis by GC or HPLC.
