Biomarker sample preparation & analysis

Fossilized organic compounds in marine sediments, also known as biomarkers, can be extracted from marine sediments using organic solvents. The total extracts are usually further separated into different fractions and further purified before analysis. We use gas chromatography and liquid chromatography coupled to mass spectrometry to quantify biomarkers of interest.
