miniature atmospheric heavy metal on-line analyzer 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.
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
the instrument is small and portable, durable, easy to maintain, accurate. it will bring reliable monitoring data, the construction costs are competitive, it is suitable for refinement of large area layout or grid monitoring.
the content of dozens of heavy metal elements such as arsenic, cadmium, chromium, antimony and mercury can be accurately measured. the detection limit of elements is low, up to 0.01ng /m3. other element models can be customized according to user’s needs.
the instrument has high sensitivity and high stability, but also has intelligent fault diagnosis and fault alarm function;
built-in calibration module, horizontal and vertical coordinate of xrf spectrum calibrate at the same time automatically, calibration frequency can be set arbitrarily, but also built-in specific metal internal standard source. it can realize automatic quality control;
through the mass flow controller, temperature and pressure sensors to control the sampling condition flow accurately and stably, and at the same time the instrument can make automatic flow calibration come true;
the equipment is based on wireless communication technology, which can realize the secure communication between the instrument and the server, and collect the big data of the environment into the "cloud platform".
monitoring data complies with the data transmission standard for online automatic monitoring (monitoring) system of pollution sources (hj/t 212-2005). at the same time, users can also easily customize the corresponding functions according to the actual needs;
professional multiple radiation protection treatment, instruments do not have any radiation leakage when it is measuring.
analysis time of sample is programmable.
