Abstract: Microwave techniques are widely used in acid digestion of solid samples. Their use in the extraction of organic analytes from environmental samples is less widespread, despite commercial devices being available for this purpose and the potential for reducing analysis time and solvent consumption. We report the use of microwave-assisted extraction (MAE) of biomarkers (chlorins and long-chain C37 alkenones), which are used as palaeoclimatic proxies in marine sediments. Factorial design was applied to determine the influence of temperature, volume...
