ABSTRACT:
A method for isolating kerogen from a mineral sample in a pressurized reaction cell, which permits reaction at pressures greater than two atmospheres and provides for the removal of all liquids from the cell without significant loss of sample solids, employing multiple steps of addition and removal of concentrated hydrochloric acid, concentrated hydrofluoric acid, concentrated ammonium hydroxide, and deionized water.
