  • Surface-coated solid-phase microextraction device
    Patent number: 7665374
    Abstract: The present application relates to a surface-coated SPME with an extracting tip that resists breaking during analysis. Rather than utilizing a hollow fiber tip, a resilient surface coated rod is utilized. Specifically, several grooves are machined into the tip of the SPME device, allowing an adsorbent material to be retained thereon. The resulting surface coated SPME device is more rugged in laboratory use and allows for testing of analytes in chemical environments that result in failures when using fiber tipped SPME devices.
