Brief introduction XHAM-2000A atmospheric heavy metal automatic monitoring system for monitoring the metal species and concentration of airborne particulate matter in the air and urban complex environment near the boundary of industrial facilities. The monitor was collected by the roll wheel (reel-to-reel, RTR) filter paper belt, and the X - ray fluorescence spectroscopy (XRF) technique was carried out to analyze the particles on the filter paper belt. Ambient air through the particle diameter cutter for sampling and extraction to filter paper, samples are collected automatically transported to the position detection, by means of XRF technology of selected metal elements were analyzed. Analysis of the same time, the next sample collection is also carried out simultaneously. In addition to the filter paper tape transport (about 20 seconds) and the daily automatic quality inspection, sampling and analysis of the continuous implementation of synchronization. Features Sampling, analysis, and proximity to real-time reporting (once per 15,30,60120180 or 240 min); Detection limit can be up to 10pg/m3 (using 4 hour sampling time); Automatic quality inspection, alarm and control; Reliable RTR/XRF Technology: it has been applied to undersea exploration, Mars exploration, and thousands of beta ray attenuation tests; At least 23 elements are monitored at the same time, and can be extended according to user's requirement; Built in XRF standard for each sample; Automatic calibration and flow calibration every day; Can be used for fixed or mobile monitoring platform; Regional and short term emission measurements; Can be used to establish benchmarks based on health standards; Risk identification equipment hot perimeter; Can carry on the pollution source confirmation and the chemical mass balance comparison; High sensitivity and reliability (pg/m3 to g/m3); Non destructive analysis, sample filing; The relationship between metal and wind speed and wind direction can be established; Metal concentration changes that could not be detected by other standard methods;
