US Patent 12105062 Carbide-derived carbon for solid-phase micro extraction media
A system and method for utilizing a carbide-derived carbon (CDC) fiber in solid-phase micro extraction. Optically pumping the carbide-derived carbon (CDC) fiber, as compared to using thermal desorption, enhances performance of the system. CDC provides for a broad based sorbent that is insensitive to high humidity. Optical pumping may be done axially or radially on a modified gas chromatography needle. In some cases, staged, or pulsed, optical pumping is used to drive off solvent or other lower boiling compounds first and then the desorption of the remaining analytes is cleaner and the instrumentation is less likely to be overloaded.
