General description

This magnetic screw cap has been developed for the CTC instrument. The vial has a precision thread with numberous threads to force the septa against the vial to seal it to be gas tight. The center hole is designed to be used for SPME as well as standard Headspace analysis, but still offers enough surface for the magnet to transport a completely filled vial.

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.

Determination of 2-Chloroethanol as Marker for Fumigant Ethylene Oxide in Sesame Seeds by HS-SPME-GC-MS

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.

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.

Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943

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.
