Since its introduction by Pawliszyn Solid Phase Micro Extraction (SPME) has seen a tremendous development. SPME is a very effective way of automated sample preparation.
It is used for extracting organics from a matrix (solid, liquid or gaseous) into a stationary phase immobilized on a fibre. The analytes are thermally desorbed directly in the injector of a gas chromatograph. Originally mostly used for extracting solvents with excellent sensitivities from aqueous matrices the range of applications today spans from chemical and environmental to medical applications.
PAL SPME Fibres: optimized for automation
PAL SPME Fibres have been developed and optimized for the most successful SPME sampler, the PAL System Autosampler. The fibres are offered with different coatings and film thicknesses. Their excellent extraction properties have been proven for many important applications.
Choose the right Fibre for your Analytes:
Typical applications for the SPME technique are:
- Trace Analysis in foodstuffs
- Drugs and pharmaceuticals
- Herbicides / pesticides
- Medical diagnostics
- Water analysis (organics in water)
- Trace impurities in polymers and solid samples
- Solvent residues in raw materials
The type of the fibre corresponds to the polarity and the molecular weight of the analytes:
