The invention belongs to the field of chemistry and is suitable for measuring four elements including nitrogen, hydrogen, carbon and sulfur in tree moss concrete. The invention relates to a method for measuring nitrogen, hydrogen, carbon and sulfur in tree moss concrete, which comprises the following steps of: 1, quantitatively weighing tree moss concrete samples, and adding the same into a special sample cup; 2, quantitatively introducing a carrier gas (helium 0.14MPa), a power gas (argon 0.4PMPa) and a burning gas (oxygen 0.1MPa) in per 1 gram of tree moss concrete; 3, cracking the tree moss concrete at high temperature, burning in pure oxygen, and converting nitrogen, hydrogen, carbon and sulfur in the samples into gases including N2, H2O, CO2 and SO2; and 4, separating N2, H2O, CO2 and SO2 through chromatographic columns, and carrying out thermal conductivity detection on the percentages of nitrogen, hydrogen, carbon and sulfur.
