A METHOD FOR ANALYSING MICRO-LIGHT HYDROCARBON (C₂-C₉) IN ROCKS

This method is a Modification of the hydrogen extraction method of Schaefer et al.and referring to the theory of the phase balance of volatile component in solids and the discrete gas extraction suggested by Kolb. This method can be used to determine C₂-C₉ hydrocarbons in the sedimentary rocks, limestone etc. The limit of detection is I ppb. The error in determination of the total amount (C₂-C₉) is 20%.
