Overview of Recent Development of Needle-Trap Devices for Analysis of Volatile Compounds

Needle-trap devices (NTDs) are another sorbent-based tool in the haystack of methods used analytical extractions. Syringe needles, similar to those for gas chromatography (GC) injection, can be partially filled with suitable sorbents and extracting collecting volatile organics, followed by injection into a GC instrument via thermal desorption. Although NTDs share many similarities advantages solid-phase microextraction (SPME), larger sorbent bed provides robustness offers potentially exhaustive This month, we take look at principles applications NTDs, recent developments their use.
