Abstract

The invention relates to an analytical device of an online aerosol carbon component acquisition analyzer. The analytical device comprises an analytical device body, a thermal insulation shell, a reflected-laser photoelectric detection joint, a transmitted-laser photoelectric detection joint, a reflected-laser photoelectric detection system and a transmitted-laser photoelectric detection system, wherein the analytical device body is positioned in the thermal insulation shell, and both the reflected-laser photoelectric detection joint and the transmitted-laser photoelectric detection joint are positioned outside the thermal insulation shell; one end of the analytical device body penetrates out of the thermal insulation shell to be fixedly connected with the reflected-laser photoelectric detection joint, and the reflected-laser photoelectric detection system is fixedly arranged in the reflected-laser photoelectric detection joint; the other end of the analytical device body penetrates out of the thermal insulation shell to be fixedly connected with the transmitted-laser photoelectric detection joint, and the transmitted-laser photoelectric detection system is fixedly arranged in the transmitted-laser photoelectric detection joint. The analytical device can reflect the change of blackness of a quartz film in the thickness direction, can also reflect the change of blackness of the surface of the quartz film, and therefore can comprehensively judge OC/EC split points.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to an analysis device for an online aerosol carbonaceous component collection analyzer. Background technique [0002] Carbonaceous components in atmospheric aerosols usually account for 10%-70% of the mass concentration of atmospheric fine particles, and are an important component of atmospheric fine particles. It can be divided into three categories: organic carbon (Organic Carbon, OC), elemental carbon (Elemental Carbon, EC) and carbonic acid carbon (Carbonate Carbon, CC). OC refers to a mixture containing hundreds of organic compounds (such as aliphatics, aromatics, acids, etc.), mainly from the emissions and biological emissions of the primary combustion process, and the participation of gaseous organic pollutants in photochemical reactions and gas particle conversion. Secondary organic carbon formed later. EC, also known as black carbon (Black Carbon, BC), usually refe...
