==Hydrogen index==
The hydrogen index (HI) represents the amount of hydrogen relative to the amount of organic carbon present in a sample. The [[/Rock-Eval_pyrolysis#Rock-eval_pyrolysis|S2 curve]] of a Rock-Eval analysis can help us determine the total amount of hydrogen in milligrams of hydrogen to grams of sample according to the following formula:
The hydrogen index (HI) represents the amount of hydrogen relative to the amount of organic carbon present in a sample. The [[Rock-Eval_pyrolysis#Rock-eval_pyrolysis|S2 curve]] of a Rock-Eval analysis can help us determine the total amount of hydrogen in milligrams of hydrogen to grams of sample according to the following formula:
:<math>\mbox{HI} = \mbox{S2} \mbox{ (Mg/g)}/\%\mbox{TOC} \times 100</math>
:<math>\mbox{HI} = \mbox{S2} \mbox{ (Mg/g)}/\%\mbox{TOC} \times 100</math>
