Abstract

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.

Description

technical field [0001] The invention belongs to the field of chemistry and is suitable for the determination of nitrogen, hydrogen, carbon and sulfur in tree moss extract. Background technique [0002] The tree moss extract is obtained by extracting the tree moss growing on Pinaceae plants with organic solvents such as ethanol and propylene glycol. The extract is brown and viscous liquid. The English name: Tree moss concrete has a pine aroma. Tree moss extract is a natural plant extract with high economic benefits and a wide range of uses. It is an indispensable additive for cigarettes, food, and daily chemicals. Tree moss extract is mainly used in the production of cigarettes. It is a fixative for cigarettes. It can endow cigarettes with a fragrance similar to pine moss. comfort. [0003] Compared with foreign blended cigarettes, the blended cigarettes in our country are not very coordinated with the aroma and flavoring, and cannot achieve the desired effect of being inte...
