designed for rapid rohs/elv compliance and halogen-free analysis, the lanscientific scopex csa high-level analyzer utilizes superior testing technology, innovative x-ray optics design and an intelligent software system to quickly and reliably determine whether a sample contains hazardous substances. it has the advantages of simple sample preparation, high analysis accuracy, wide range of analyzable elements, simple and rapid testing, etc., and the results are reliable and accurate, in line with the new national standard.
how scopex works
wave sound scopex energy dispersive x-ray fluorescence spectrometer uses the principle of x-ray fluorescence analysis.
the principle of x-ray fluorescence analysis
by irradiating the sample with x ray of a certain wavelength, the element is in the excited state and produces excited photons, forming a kind of fluorescence x ray. the energy of the excited states of different elements is different, and the fluorescence x rays produced are different. qualitative analysis is carried out by detecting the wavelength of x-rays, and quantitative analysis is carried out by detecting the specific x-rays of the elements.
operating principle of instrument
the instrument's high-voltage power supply provides tube pressure and tube flow to the optical tube. the optical tube excites continuous x-rays, which are radiated to the sample to produce x-ray fluorescence with sample characteristics. after entering the detector, the signal becomes voltage signal, which is amplified and processed by the computer after data acquisition.

the hardware configuration
the combination of high-power and high-efficiency x-ray tube and high-performance si-pin detector brings a very low detection limit and can detect trace harmful substances quickly and accurately.with only one instrument, sample compliance monitoring can be performed with high efficiency and high quality.
accurate and reliable
xrf analysis software with wave sound, combined with empirical coefficient method, basic parameter method (fp method) and other analysis methods, the accuracy of test data performance is guaranteed.
empirical coefficient method: the instrument determines the influence coefficient according to the determination of the standard sample.the standard sample is required to be of similar type to the sample to be tested, and the calibration model is simple.
basic parameter method (fp method) : the instrument according to the actual detection of substances, through a variety of physical quantity modeling calculation to determine the parameters.the standard sample requirements are not high, the calculation is more complex, suitable for the lack of the corresponding standard sample material detection.
screening of hazardous substances
scopex provides analytical screening for hazardous metal elements that are limited by environmental regulations such as rohs/elv, and further standard halogen detection capabilities. halogen-free analysis can also be easily perfor
