SPME Fiber Performance Tips for Volatiles & Semi-Volatiles

When attempting to collect volatile analytes, the Carboxen/PDMS fiber is shown to be ideal for adsorption of volatile compounds. Adsorption type fibers are also better for extracting analytes present at low concentration levels and often provide lower MDLs for many analytes. To improve sampling of volatiles in complex matrices, place the sample
