Single‐Wall Carbon Nanotubes Used as Stationary Phase in HPLC

Abstract

The single wall carbon nanotubes (SWNTs) were first bonded to 3‐aminopropyl silica gel and used as a stationary phase in high performance liquid chromatography. With different mobile phases, seven polycyclic aromatic hydrocarbons were separated. The results showed that SWNTs had a stronger interaction between the aromatic group and SWNTs. This work indicated that SWNTs make it possible to extend the application range on the newly prepared chromatographic stationary phases for HPLC.
