Abstract：The classical analytic method for the ultimate analysis of coal were introduced including Gravimetric method measuring hydrogen, semi-micro Macro Kjeldahl method measuring nitrogen, Eschka method or high-temperature combustion coulometric method measuring sulphur.The basic principle of the element analyzer method was expounded.The advantages and disadvantages of the classical method the elemental analyzer method were compared, it was indicated that by observing the correction factor and the volatility of nitrogen content integral the filler in oxidation tube and reduction tube can be replaced reasonably.
