摘要
讨论各种类型碳吸附剂(活性炭、碳分子筛、石墨化炭黑和碳纳米材料)用作气相色谱固定相的演变。除硅胶以外,碳是气相色谱出现以来最早使用的固定相,起初主要是使用工业活性炭,后来对其改性以便改善和适应色谱分离性能。近年来,把各种类型的碳纳米材料(富勒烯、碳纳米管、石墨烯)用于气相色谱固定相。
The evolution of various types of carbon adsorbents（ active carbons,carbon molecular sieves,graphitized carbon black and carbon nano materials） used as GC stationary phase are discussed. Besides silica gels,active carbons have been used since GC was introduced. At first,mainly industrial active carbons were used but after a time they were modified to adjust their properties for chromatographic separation requirements. Recent years various types of carbon nanomaterials such as fullerenes,carbon nanotubes,graphene were used as GC stationary phases.
