General description
应用：该色谱柱的低极性接近于角鲨烷，使其实际上比现有被广泛使用的非极性聚二甲基硅氧烷柱具有更低的极性。与非极性和中极性色谱柱相比，该柱具有独特的选择性，并可用于含PCB样品的验证性分析。

SPB®-Octyl Capillary GC Column has high resolution and it provides reliable congener separations.
Application
SPB®-Octyl Capillary GC Column was used in solid-phase microextraction-capillary gas chromatography combined with microwave-induced plasma atomic-emission spectrometry (GC-MIP-AED), for speciation of selenite (SE(IV)) as it is an element which is essential at low levels and is considered at higher levels.
Utilized in US EPA Method 23: Determinationof Polychlorinated Dibenzo-p-Dioxins, Polychlorinated Dibenzofurans,Polychlorinated Biphenyls, and Polycyclic Aromatic Hydrocarbons from StationarySources
Other Notes
We offer a variety of chromatography accessories including analytical syringes
