General description

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是一种绿色的样品制备技术，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。

Other Notes

外观可能会有所不同。较暗的斑点可能在纤维上可见，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。

Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943

High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination in terms of sensitivity and selectivity.
