Description
The Hydrogen-Eval® is the first worldwide fully automated Vinci instrument (patents owner) that performs geochemical analysis on natural hydrogen source rocks. The powerful device, determines via high-temperature pyrolysis the source rock hydrogen potential whether if the source rock is organic matter-rich (ex: coal, marine source rock, lacustrine source rock) or iron-rich (BIF, Olivine…). To do so, two setups are available on this device: one dry carrier gas mode for organic rich samples and a wet carrier gas mode used for iron-rich samples. The Hydrogen Eval provide critical parameters as S2 H2 (hydrogen potential) and temperature peak generation which allows the determination of the hydrogen origin and kinetics parameters essential in generation modelling. Specifically, the hydrogen is measured by a TDLAS detector, which is an advanced spectroscopic detection system very sensitive for symmetric molecules as H2. Data from the Hydrogen Eval can be input into the Vinci interpretation software.
