VALIDAÇÃO DE UM MÉTODO ANALÍTICO PARA DETERMINAÇÃO DE MARCADORES ORGÂNICOS GEOQUÍMICOS EM AMOSTRAS DE SEDIMENTOS MARINHOS

This paper describes the validation of an alternative method for determination of n-alkanes, sterols (OLs) and n-alkanols (ALCs) in marine sediments, through adaptation of clean up. The method reduced the material consumption, the discards produced and working time. The recovery percentages were 60-...
