请问您使用过thin film SPME薄膜固相微萃取吗？

Thin Film Solid Phase Micro-Extraction (TF-SPME), TF-SPME is an extension of regular SPME. It is more sensitive than regular SPME due to the increased surface area and phase volume, both of which lead to improved analyte recovery. The TF-SPME device is a 20 mm x 4.8 mm carbon mesh sheet impregnated with a sorptive phase. The TF-SPME devices can be used in headspace or immersive mode.
