1. A method of solid-phase micro-extraction, comprising:
providing a gas chromatograph (GC) needle comprising a carbide-derived carbon (CDC) fiber;
subjecting a sample to be analyzed comprising one or more analytes to the needle comprising the carbide-derived carbon (CDC) fiber;
inserting the needle into the injection port of a detection system comprising a gas chromatograph, wherein the injection port comprises a glass insert liner with a metal coating on the glass insert's inner diameter; and
desorbing the one or more analytes from the needle comprising the carbide-derived carbon (CDC) fiber core using a heated injection port,
wherein the needle further comprises an inner sheath and an outer sheath.
