SPME fibers with Carboxen®/Polydimethylsiloxane (CAR/PDMS) and Polydimethylsiloxane/ Divinylbenzene (PDMS/DVB) coatings are now available on a nitinol core (NIT) in a SS assembly for improved fiber performance. Selectivity of the CAR/PDMS and PDMS/DVB SPME fibers has been maintained for seamless transition of methods from fused-silica core (FS) fibers to the improved NIT technology.

NIT fibers offer the following benefits:

  • Enhanced fiber reproducibility
  • Greater fiber durability
  • Maintained selectivity for method consistency
  • Core inertness to ensure analyte stability
