Supertech Graphitized Carbon Black (GCB)

Supertech Graphitized carbon black material is non-porous, which is prepared at temperatures >2500 °C, resulting in highly pure products that ensure effective release/desorption of analytes of interest. Carbon surface comprised of hexagonal ring structures, interconnected and layered into graphitic sheets. Extreme affinity for organic polar and non-polar compounds from both non-polar and polar matrices when used under reversed-phase conditions. It exhibits hydrophobic surface characteristics, meaning that small, polar molecules such as water are not adsorbed, allowing them to be effectively used to trap organic compounds despite high humidity. Moreover, its surface area is about 100 m²/g, so it can be used for removing pigment effectively, while it can provide high recoveries of analytes. Independent investigators have found supertech-Carb extremely useful for the rapid sample preparation of over 500 pesticides from various matrices including ground water, fruits and vegetable.

超高科技石墨化碳材料是无孔的,在> 2500℃的温度下制备，产生高纯度的产物，确保所关注的分析物的有效释放/解吸。 碳表面由六角环结构组成，互连并分层成石墨片。 当在反相条件下使用时，极性亲和力来自非极性和极性基质的有机极性和非极性化合物。 它表现出疏水的表面特性，这意味着小的极性分子如水不被吸附，允许它们被有效地用于捕获有机化合物，尽管高湿度。 此外，其表面积为约100m 2 / g，因此其可用于有效地除去颜料，同时其可提供高分析物的回收率。独立研究人员发现supertech-Carb对从包括地下水，水果和蔬菜在内的各种基质中超过500种农药的快速样品制备非常有用。
