product introduction

atmospheric heavy metal on-line monitor is lanscientific co., ltd., fusion x fluorescence nondestructive testing technology, automatic air particulates enrichment technology, independent research and development of the monitoring instrument miniaturization, the advantages of small size, low detection limit, several accurate, high temporal resolution, which can realize the air particulate matter of heavy metals such as lead, cadmium, chromium, arsenic continuous monitoring, the stationing, suitable for grid, intensive is widely applied to urban atmospheric environment monitoring, the plant unorganized emissions, traffic exhaust gas pollution monitoring, emergency monitoring, etc.

the product principle

after stimulated with x-ray bombardment sample, sample produce x-ray fluorescence, x-ray often the element layer atomic layer k and l up the inner electron atoms, outer electrons fill holes are high-energy, added to the low energy high-energy electrons orbit the excess energy by x ray fluorescence radiation, the radiation of spectral line contains the characteristics of the various elements, like fingerprints, and independent of the chemical valence state of the atom. the intensity of the radiation is proportional to the concentration of the element in the sample.

application range

on-line monitoring of nuclear radiation at radiation monitoring stations

on-line heavy metal detection after solid waste or waste incineration

rapid detection of heavy metals in automobile exhaust

environmental assessment, permit

location of pollution source, traceability pollution forecast and early warning

other field test and test enforcement

emergency emergency monitoring
