Where, K is the photon energy of the incident radiation; Q corresponding charge amount generated by the detector; k for the response parameters of different types of energy detectors. The amount of charge proportional to the energy of the incident radiation, so by measuring the amount of charge available analyte feature information. Characteristic spectral lines measured elements need to adopt certain excitation source to get. Currently excitation source conventionally used mainly ray tube and isotope excitation sources. In order to obtain qualitative and quantitative information of the sample, in addition to the spectrometer, but also must adopt certain sample preparation techniques ROHS, and the strength of the obtained spectral correlation analysis and data processing. 3 Technical Specifications Edit Elemental analysis range from sulfur (S) to uranium (U) Elements of harmful elements in the range of 1 PPm to 99.99% RoHS Directive (restriction Cd / Pb / Cr / Hg / Br) detection limit up 1PPM ; multiple collimator automatically switch freely Triple safety protection mode Independent matrix effect correction model of multi-variable nonlinear regression program sample chamber automatically switch software localization sample platform seedlings ROHS detector, minimum displacement 0.01 mm automatic collimator and filter switch ray 3VROHS instrument three values ??were developed specifically for different sample measurement software, user interface is very friendly and built-in high definition camera, easy for users to test samples of noble stylish, bring you a new visual impact Shui ROHS instrument | ROHS | Sheng Ding instrument provided by the Dongguan City Ding Sheng Precision Instrument Company.
