Product Name: Fischer FISCHER XULM Energy - Dispersive X - Ray SpectrometerPurpose: It is suitable for non - destructive measurement of coating thickness and composition analysis on small parts, and can be used in scenarios such as quality control, incoming inspection, and production process control. It is often used for coating measurement in the circuit board industry, coating measurement of connectors and contacts in the electronics industry, relevant measurements in the jewelry and watch industry, and determination of metal content in electroplating baths.Technical Principle: It uses X - ray fluorescence spectroscopy technology. The X - ray source emits rays to irradiate the sample, and the elements in the sample are excited to produce characteristic X - rays. The detector determines the element type and content based on the energy and intensity of the characteristic X - rays. Based on Fischer's fundamental parameter method, accurate analysis and measurement of coating systems and solid and liquid samples can be carried out without standard samples.Performance: Equipped with a micro - focus tube, the minimum measurement point is about 100μm. The proportional receiver achieves a high count rate to ensure high - precision measurement. It can electrically adjust multiple collimators and basic filters to optimize measurement conditions. It can measure elements from chlorine (17) to uranium (92). For an ultra - thin gold coating of 80nm, when measured with a Ø0.25mm collimator, the repeatability accuracy within 20 seconds can reach 2.5nm. Although it has a compact structure, it has a spacious measuring chamber and can measure large - volume samples.
