PHECDA-ECO Portable High Sensitivity XRF Heavy Metal Analyzer Features
Monochromatic aggregation excitation technology
The high-sensitivity XRF heavy metal analyzer uses a hyperboloid curved monochromator to optimize the excitation efficiency of the element and reduce the background of the continuous scattering lines of the X-ray tube to improve the signal-to-noise ratio of the element's fluorescent rays.
2. Using the highest performance SDD detector Silicon drift detector (SDD) is the core component of the energy dispersive X-ray fluorescence spectrometer. Its performance depends on the crystal area, the highest counting rate, and resolution. The PHECDA series uses the highest performance SDD detection today. To ensure elemental analysis performance.
3. Fast FP algorithm
The difficulty of XRF analysis is that the intensity of elemental fluorescence is not only related to the content of elements in the sample, but also to the content of other elements. This is the so-called matrix absorption-enhancement effect, and this physical effect makes it difficult to choose a suitable standard sample. The matrix of the selected standard sample is inconsistent and cannot cover the content range of each element of the sample to be tested, which will cause errors to the actual sample analysis. Fundamental parameters method calculates the X-ray fluorescence spectrum from generation to detection and establishes corresponding mathematical models. The basic parameter method eliminates background differences caused by different types of sample substrates and reduces analysis errors. Elemental quantitative analysis results can be obtained by calibrating a few standards.
4. Optimizing the detection capability of cadmium Cadmium is a toxic heavy metal, which has attracted much attention in the fields of environmental protection and food safety. Conventional XRF has challenges in exciting and detecting cadmium (Kα: 23.1KeV). The monochromatic focus of cadmium stimulates the detection limit of cadmium to an unprecedented level of 0.05 mg / kg.
