Abstract

The invention discloses an atmospheric dust phase real-time analytic system which comprises a suction filtration window and a suction filtration device, wherein a filter film strip is arranged between the suction filtration window and the suction filtration device, the filter film strip is driven by a conveying device which is controlled by an electric control system; and the filter film strip is further conveyed in front of a detector window of an X-ray diffraction analytic device by the conveying device for carrying out real-time analysis on the dust sample. The atmospheric dust is collected and enriched in different ways, so that the analytic and detection method is enriched, the layered analytic function to samples is provided, the detection limit of the system is enhanced, the phase analysis of inorganic components and organic components of the airborne dust is realized, the collection and remote control of analytic data are convenient, the system is beneficial to analysis monitoring of airborne and investigation and management of atmospheric environment, so the system has high values in application and promotion.

Description

[0001] technical field [0002] The invention belongs to the field of airborne dust monitoring, in particular to a real-time phase analysis system for airborne dust. The system is suitable for installation in various fixed locations and equipped with various mobile platforms. It is easy for multi-point arming and remote multi-point data collection, so as to realize real-time analysis and monitoring of organic and inorganic floating dust particles in different areas and different periods of time. Background technique [0003] At present, remote collection and preparation and real-time phase analysis cannot be carried out on airborne dust samples. [0004] Chen Bo et al. disclosed the use of hydrofluoric acid-hydrochloric acid-nitric acid-perchloric acid system on the air filter membrane to adhere to The floating dust sample is decomposed, and then the method of inductively coupled plasma emission spectrometry and inductively coupled plasma mass spectrometry is used to simult...
