Abstract

The invention discloses a multifunctional automatic acquisition and sample preparation system for airborne dust. The multifunctional automatic acquisition and sample preparation system comprises a suction filtration window and a suction filtration device, wherein a filterable membrane band is arranged between the suction filtration window and the suction filtration device and is driven by a conveying device, and the conveying device is controlled by an electric control system; a printer, a thermoplastic membrane packaging device and a filterable membrane sample storage room are arranged in the system, wherein the printer is used for printing marks on the filterable membrane band, the thermoplastic membrane packaging device is used for carrying out plastic packaging on a sampled filterable membrane sample, and the filterable membrane sample storage room is used for storing the plastic-packaged filterable membrane sample; and the system further comprises a gas flowmeter. According to the multifunctional automatic acquisition and sample preparation system, the fixation, acquisition, preparation, marking, sealing and storage of the filterable membrane sample can be automatically carried out, so that the quality in the acquisition and preparation of the sample is improved, the uniqueness and representativeness of the sample and the stability of the physical and chemical properties of the sample are guaranteed, and the requirements on the sample in modern analytical detection are met. The system is provided with devices for being connected and fixed with other analytical equipment, and communication and numerical control interfaces of the devices, so that the effects of the remote automatic acquisition and preparation and real-time detection and analysis of airborne dust samples are realized.

Description

[0001] technical field [0002] The invention belongs to the field of airborne dust monitoring, in particular to a multifunctional automatic collection and sample preparation system for airborne dust. Background technique [0003] At present, remote automatic collection and preparation of atmospheric dust samples cannot be performed. [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 simultaneously measure the atmospheric floating dust, but there are still the above shortcomings. Contents of the invention [0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a multi-functional automatic collection and sample preparation system for a...
