Problems solved by technology

The disadvantage is that the adsorption device will adsorb a part of the non-volatile particles, which will reduce the passing rate.
Moreover, the design components of these instruments are relatively complex and costly, and it is difficult to meet the long-term stable observation requirements

Description

technical field [0001] The invention relates to atmospheric aerosol volatile characteristic detection equipment, in particular to a gas temperature control system and application of an atmospheric aerosol volatile characteristic measuring instrument. Background technique [0002] Atmospheric aerosols directly affect the Earth's atmospheric radiation balance by scattering and absorbing radiation. The chemical composition and mixing state of aerosol particles in the atmosphere are very complex, and the optical effects and radiation effects of aerosols are closely related to the chemical composition and mixing state of the particles. Based on the characteristic that different chemical substances volatilize at different temperatures, this instrument detects the volatilization degree of the particles and infers the chemical composition and mixing state by measuring the change and distribution of the particle size of the aerosol particles before and after heating. The atmospheric...
