A new automatic apparatus for the Pregls micro-determination of carbon and hydrogen was described.The moving furnace, 8cm long, was moved 13 mm/min.by a cynchronized motor, but it was stopped by a relay whenever the pressure in the combustion tube was increased.Thus, the furnace did not move until it was heated to the maximum temperature, and it was stopped also when the sample was evaporated or oxidized.Therfore, the sample was burnt not rapidly but gradually.The relay was composed of a fine capillary and a manometer which contained a 33% KOH solution.Analytical data on test samples were satifactory, and the data given by this apparatus on 100 unknown samples showed good coincidences with that given by the usual apparatus and skilful analysts.
