Introduction In view of the increasing pollution of heavy metals in the atmosphere, the development experience of the combined technology and safety testing instruments and the latest needs of users at home and abroad, the new generation of AMMS-100 atmospheric heavy metal analyzer was introduced by X ray fluorescence technology. The instrument can be widely used in the monitoring of lead, mercury, chromium, cadmium, arsenic and other heavy metal pollutants in the PM10, PM2.5 and TSP in the environmental air quality monitoring sites in the industrial pollution area, residential area, background station and so on. Product principle: X ray fluorescence analysis of the content of metal elements in the air filter membrane is the recommended method of EPA. Instrument adopts precision constant current sampler for sampling, precise control of the acquisition of the volume of air, at the same time, through the membrane enriched air of heavy metal pollutants. XRF (X ray fluorescence) technique is used to analyze the heavy metal pollutants quickly and without damage. Features 1 can simultaneously monitor 26 elements; 2 detection limit is low: up to ng/m level; 3 non destructive testing, membrane samples can be saved; 4 sampling and analysis time programmable (10 ~ 4000) min optional; 5 can be combined with conventional air station, mobile monitoring vehicles and other components of the environmental air quality monitoring system, to achieve the on-line monitoring of heavy metal pollution. Technical parameter Measurement principle X ray fluorescence method (EPA-IO3.3) Monitoring the main elements Pb (lead), CD (cadmium), Hg (mercury), arsenic (arsenic), Cr (CR), Cu (copper), Zn (zinc), Ni (nickel), BA (BA), a (silver), Se (selenium), Br (BR), sb (sb), Sn (TIN), Ti (titanium), CO (CO), Mn (MN), Zr (Zr), Ca (calcium), K (potassium), Fe (iron), Rb (RB), Mo (molybdenum), V (V), SC (SC), Pd (PD), GA (GA) and CS (CS) Measurement range (0 ~ 100) ug/m3 The detection limit can reach ng/m3 level (sample time 2 h, flow rate 16.7 L/min).
