Validation of a rapid and simple method for the preparation of aqueous organic compounds prior to compound specific isotope analysis

The comparative extraction of landfill leachate using SPE and LLE indicated SPE generally extracts slightly more of each compound from leachate than LLE. This relationship is stronger than for polar compounds. In addition, the δD composition of each compound prepared using SPE was with two standard deviations of the sample compound prepared using LLE, and the δ13C composition of each compound prepare using either method was mostly within two standard deviations.
