  • Method for making SPME fibers
    Patent number: 8230703
    Abstract: It is disclosed a method for making SPME fibers. The SPME fibers consist of metal-oxide coatings on fused-silica fibers. The coatings are prepared from a water-based solution containing a predetermined amount of metal ion and a predetermined amount of a reactant. The water based solution and the fused-silica fibers are kept at the temperatures below 100° C. for a predetermined time to obtain SPME fibers. The SPME fibers are applied for extraction of pesticides and other organic compounds such as 1,4-dichloro-2-nitrobenzene; Biphenyl; and Acenaphthene in the water based solution and cooling gas of a power generator respectively.
