Thin Film SPME
Thin film solid phase microextraction , TF-SPME or Thin Film SPME , is a new solid phase microextraction technology which spreads the multicomponent sorptive phase on the carbon mesh. It was invented by Professor Janusz Pawliszyn, University of Waterloo and Academician of The Royal Academy of Sciences of Canada, and concentration of VOCs and SVOCs combined with GC/MS.
TF-SPME can greatly improve the sensitivity by increasing the volume and surface area of the extraction phase without sacrificing the analysis time. It solves the problem of the limitation of absorption rate and absorption capacity existing in the traditional solid-phase microextraction process. It is a new extraction and concentration technology with extensive application, which is combined with GC / MS, especially suitable for food, perfume, beverage, environmental monitoring and other industries.
TF-SPME is stronger and more durable than SPME. It can be used for on-site sampling. It has strong compatibility with the samples in harsh environment. It can be used for the extraction of target substances such as sewage and lake water. It can also be used for the detection of food flavor substances. The extraction volume is large and the extraction time is short.
After extraction, TF-SPME can be desorbed by solvent stripping or thermal desorption equipment and then enter the gas quality system for detection. It is a kind of Environmental friendly sampling equipment and analytical methods to promote the application of green analytical chemistry.
Suitable for a wider range of polar and non-polar compounds and the trace volatile organic compounds
Larger phase surface area / volume ratio, high extraction efficiency and high sensitivity
Robust membrane design for sampling environmental samples
Green environmental protection technology of solvent free extraction
