Descrição geral
Uma fase menos hidrofóbica que a C18. Proporciona menos retenção de compostos polares e apolares que a C18. Use uma fase móvel contendo 5% menos modificador orgânico para a coluna C8 que para a C18. Os compostos polares são, relativamente, mais fortemente retidos nas colunas C8 que nas colunas C18.

Explosives such as 2,4,6-trinitrotoluene (TNT), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) are widely distributed environmental contaminants. Complete chromatographic separation is necessary in order to accurately determine and quantify explosives and their degradation products in environmental samples and in (bio)transformation studies.
