The new Finneran SPME Vials with a thicker lip are ideal for most SPME applications. The thicker lip vial creates a tighter seal on the vial. The Finneran SPME vials are manufactured from high quality Type I borosilicate glass. This new thicker lip vial is available in 10mL and 20mL capacities. To.

Aug 1, 2000 · Two Headspace SPME methods were developed and optimized: one for the extraction from aqueous solutions, and the other for the extraction from organic solutions (N,N-dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO). The optimum equilibration time for all components and all systems was 30 min.

SPME MicroCenter Caps and Septa Micro-thin septum center pierces easily without bending needles or breaking SPME fibers. Thicker outer septum wall secures septum in place and ensures a tight seal. Versatile closures are suitable for SPME as well as dynamic and static headspace applications.

Headspace sampling sensitivity is best when the headspace volume is small. We recommend keeping the headspace volume between 30% and 50% of the vial. When the headspace volume is small the fiber extracts more sample, faster, and with greater efficiency. You can use a larger headspace volume in some cases with high concentration samples.

Aug 1, 2022 · Having this in mind, one of the most widespread SPME modes is the headspace-SPME (HS-SPME), which consists of the extraction from the HS phase equilibrated with the sample ( Fig. 1 ). HS-SPME provides one of the best platforms for sample preparation, mainly for the analysis of volatile (VOC) and semi-volatile organic compounds (SVOC) [12].
