一般描述

我们竭诚为您带来绿色替代产品，以符合绿色化学12项原则的一项或多项要求。本品为固相微萃取(SPME)技术产品。SPME是绿色环保的样品制备技术，包括采用无溶剂萃取技术、SPME纤维萃取头可重新利用、产生的废弃物极少，符合“废物预防”和“安全的溶剂和助剂”原则。点击 此处 以获取更多信息。

应用

SPME纤维束二乙烯基苯/羧基/聚二甲硅氧烷(DVB/CAR/PDMS)用于通过顶空-固相微萃取法以及气相色谱与质谱联用的方法分析历史性塑料和橡胶材料的VOC排放。

特点和优势

设计与 Merlin Microseal 密封系统结合使用；可与其他无隔垫的系统一起使用。

其他说明

外观可能会有所不同。纤维头上可能可见较暗的斑点，但不会影响性能。
键合到柔性熔融石英芯层上的涂层，在更不易断裂的萃取头上获得更合适的涂层。与在标准熔融石英芯层上的同样涂层相比，在萃取选择性上略有区别。
