Hydrothermal vents offer a continuous supply of reactive nutrients which react with transition metal minerals. The combination of high pressure, a temperature gradient and a nearly neutral pH can lead to a high diversity of organic molecules including amino acids, hydroxy acids, fatty acids and small peptides [1-3]. In depth analysis of these complex reaction mixtures requires high-resolving analytical tools [4,5] and sophisticated approaches [6]. The combination of FT-ICR-MS, GC-MS and NMR methods have provided a complementary profile of the products for both low and high molecular weight compounds, including an unexpected variety of CHOS derivatives. In summary, high-resolving analytical methods expand our view into the fascinating chemistry of a potential origin of life scenario under hydrothermal vent conditions. [1] C. Huber, G.
