A METHOD FOR DETERMINING THE STRUCTURE OF ORGANIC COMPOUNDS HAVING FUNTIONAL GROUPS COMPRISING: (A) INJECTING A SAMPLE OF SUCH AN ORGANIC COMPOUND DIRECTLY INTO A BODY OF HEATED HYDROGENATION CATALYST WHILE PASSING A STREAM OF HYDROGEN GAS THROUGH SAID BODY OF HEATED CATALYST TO REMOVE SAID FUNCTIONAL GROUPS AND PRODUCE REACTION PRODUCTS OF THE GROUP CONSISTING OF THE PARENT HYDROCARBON, THE NEXT LOWER HOMOLOGUE OF SAID PARENT HYDROCARBON, AND FRAGMENTS THEREOF; (B) PASSING THE REACTION PRODUCTS THROUGH A CHROMATOGRAPHIC COLUMN; (C) ELUTING THE REACTION PRODUCTS FROM THE COLUMN WITH A STREAM OF GAS; (D) PASSING SAID STREAM OF GAS THROUGH A DETECTING ZONE TO DETECT THE PRESENCE OF REACTION PRODUCTS CARRIED BY SAID GAS; (E) RECORDING THE RETENTION TIME OF THE REACTION PRODUCTS ON SAID COLUMN; AND (F) COMPARING SAID RETENTION TIME WITH THE RETENTION TIME OF COMPOUNDS OF KNOW STRUCTURE, ALL OF THE FOREGOING STEPS, EXCEPT THE LAST, TAKING PLACE AS A SINGLE SEQUENTIAL OPERATION.
