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無(wú)孔的,在> 2500℃的溫度下制備，產(chǎn)生高純度的產(chǎn)物，確保所關(guān)注的分析物的有效釋放/解吸。 碳表面由六角環(huán)結(jié)構(gòu)組成，互連并分層成石墨片。 當(dāng)在反相條件下使用時(shí)，極性親和力來(lái)自非極性和極性基質(zhì)的有機(jī)極性和非極性化合物。 它表現(xiàn)出疏水的表面特性，這意味著小的極性分子如水不被吸附，允許它們被有效地用于捕獲有機(jī)化合物，盡管高濕度。 此外，其表面積為約100m 2 / g，因此其可用于有效地除去顏料，同時(shí)其可提供高分析物的回收率。獨(dú)立研究人員發(fā)現(xiàn)supertech-Carb對(duì)從包括地下水，水果和蔬菜在內(nèi)的各種基質(zhì)中超過(guò)500種農(nóng)藥的快速樣品制備非常有用。
