A sampling swab useful in trace analyte detection is provided. The sampling swab possesses absorption/adsorption and desorption properties suitable for use trace analyte sample collection. The sampling swab is also capable of withstanding repeated mechanical stress and heat treatment. Methods for producing a sampling swab that is substantially free of impurities that interfere with analyte detection, but which remains sufficiently resistant to degradation by mechanical and heat stress are also provided. |
