Solid phase microextraction fiber cleaning and conditioning apparatus and method
Abstract
A SPME-fiber cleaning and conditioning apparatus and method having an elongated heating chamber with first and second opposite ends. The first end is capable of insertably receiving a SPME fiber portion of a SPME device, and the second end is a fluid outlet. A heater is provided for heating the chamber and heat-treating an inserted SPME fiber. Contaminants and other particles are agitated, desorbed and purged from the inserted SPME fiber by flowing a fluid through the chamber from the first end to the second end, away from the SPME device. Additionally, turbulence may be produced in the flow at a location adjacent the first end, to enhance agitation, desorption, and purging. A holder may also be provided extending from the first end for supporting the SPME device in a substantially horizontal orientation when the SPME fiber is positioned in the chamber.
