Articles
Study demonstrates SPME of BPA from an energy drink using an overcoated PDMS/DVB fiber, followed by GC/MS/MS analysis.
The work describes the development of an HS-SPME-GC-MS method to determine 2-chloroethanol as a marker of fumigant ethylene oxide in different kinds of sesame seed samples.
Protocols
Overcoated SPME fiber enables low-level BPA analysis in food via SPME-GC-MS/MS, meeting tighter migration limit regulations.
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination in terms of sensitivity and selectivity.
