SPME Arrows
Solid phase microextraction (SPME) is a solvent-free sample preparation technology. Based on the principle of adsorption or absorption and desorption, SPME uses a coated fiber or arrow to concentrate volatile and semi-volatile compounds from a sample. In SPME, analytes establish equilibria among the sample matrix, the headspace above the sample, and the polymer-coated fused phase.
With the increase in wildfires over various regions around the globe, many growers and wineries continue to worry about smoke impact in grapes and their wine. Agilent has developed a solid phase microextraction (SPME) gas chromatography/mass spectrometry (GC/MS) method to analyze the free-form volatile phenols associated with smoke impact. The Agilent SPME-GC/MS/MS method for the analysis of free-form volatile phenols associated with smoke impact allows for confident identification and reliable quantitation.
Determination of the typical off-odor substances in drinking water, 2-methyl isobutyl alcohol (2-MIB) and geosmin, using a SPME device with gas chromatography/mass spectrometry (GC/MS) detection is described, and applied to the control of actual water samples. Advantages demonstrated include:
Robust SPME Arrows provide high sensitivity, and rugged and reproducible quantitative determinations
Green method eliminates the use of organic solvents, reduces environmental pollution, and protects operator safety
Method requires small sample volumes, exhibits less interference by the matrix, and is easy to deploy for online monitoring
The used SPME Arrow is robust and last for several hundreds of analyses and GC/MS injections
