一般描述
浓缩和储存源自水的分析物；采样室内空气 — 该固相微萃取便携式现场采样器是从现场样品中萃取和输送挥发性和半挥发性化合物的高效且经济的方法。使用便携式现场采样器萃取并储存的杀虫剂化合物引起的样品损失比起储存整个水样引起的样品损失要明显的小。该采样器可重复使用 50-100 次，当萃取头无法再次使用时可以丢弃。
该便携式现场采样器也可有效地检测空气中的有机化合物。根据我们的研究，该采样器可监测实验室空气中 ppb 水平的典型高效液相色谱和气相色谱溶剂。有四种萃取头：
用于挥发性物质痕量分析的聚二甲基硅氧烷 (PDMS)/Carboxen 萃取头、常规用途的 PDMS 萃取头、用于半挥发性和较高挥发性物质分析的 PDMS/DVB 萃取头以及用于极性半挥发性物质的 Carbowax/DVB 萃取头。
针头导向器/测深仪上的五个插槽控制针头插入样品容器中或在纤维解吸时插入进样端口中的深度。
组件包含 24 号针头。可定制 23 号针头和其他涂层。

In this study the effect of the cultivar on the volatile profile of five different banana varieties was evaluated and determined by dynamic headspace solid-phase microextraction (dHS-SPME) combined with one-dimensional gas chromatography-mass spectrometry (1D-GC-qMS). This approach allowed the definition of
